Polyphenolic phytochemicals, especially the ubiquitous flavonoid class of polyphenols, are able to bolster the human immune system in response to common food allergens. Unbound, free dietary polyphenols released during digestion after dietary intake of polyphenol-rich foods mitigate oxidative stress and inflammation provoked during an allergic reaction, but these molecules can also stabilize specific human allergic effector cells (mast cells, basophils) involved in the cascade of allergy symptoms. Polyphenols bound, non-covalently or covalently, to allergenic food proteins using food-compatible methods result in protein-polyphenol particulate complexes. The protein-polyphenol complexes deliver the same allergy-attenuation mechanisms as free polyphenols, but also have the capacity to mask allergenic epitopes on proteins and change protein conformation to reduce IgE recognition. Protein-polyphenol complexes are also capable of protecting ephemeral polyphenol molecules during transit in the human gastrointestinal tract, for delivery to the gut microbiome.}, booktitle={Encyclopedia of Food Allergy.

The spray drying process was evaluated (solids recovery SR and polyphenol retention PR) and the four experimental protein-polyphenol treatments IP–RM, IP-MG, IPP–RM and IPP–MG were characterized regarding their physicochemical, bioactivity, functional, bioaccessibility and thermal stability properties. Higher SR (53.7-53.3%) and PR (53.1 – 62.5%) were observed for IPP-derived particles (p<0.05). Particles had water activity in the microbiologically stable range (0.24-0.32) and high protein content (29.5%-38.3%) All particles had low hygroscopicity (<15%) and solubility between 44-52.83%. Remarkably high phenolic content (>68.5 mg GAE/g) was shown for MG-derived particles. Good emulsifying activity (1.85 to 16.46 m2/g) and emulsifying stability (> 60%), foaming capacity (4 – 57%) and foaming stability (2.0-37.3%) were observed for all insect protein-polyphenol particles. Differently from MG-derived particles, RM-derived treatments showed higher polyphenol bioaccessibility than non-complexed polyphenols (p<0.05).

SP had low total phenolic content (7.43 ± 0.23 mg GAE/g DW), but complexation with elderberry or muscadine grape pomaces polyphenols led to a substantial increase (27.63 ± 1.15 SP-EB and 111.0 ± 2.6 mg GAE/g DW SP-MG).

Epidemiological evidence suggests that anthocyanin (ANC) intake is associated with a low risk of PD. Previously, we reported that extracts enriched with ANC and proanthocyanidins (PAC) suppressed dopaminergic neuron death elicited by the PD-related toxin rotenone in a primary midbrain culture model. Here, we characterized botanical extracts enriched with a mixed profile of polyphenols, as well as a set of purified polyphenolic standards, in terms of their ability to mitigate dopaminergic cell death in midbrain cultures exposed to another PD-related toxicant, paraquat (PQ), and we examined underlying neuroprotective mechanisms. Extracts prepared from blueberries, black currants, grape seeds, grape skin, mulberries, and plums, as well as several ANC, were found to rescue dopaminergic neuron loss in PQ-treated cultures. Comparison of a subset of ANC-rich extracts for the ability to mitigate neurotoxicity elicited by PQ versus rotenone revealed that a hibiscus or plum extract was only neuroprotective in cultures exposed to rotenone or PQ, respectively. Several extracts or compounds with the ability to protect against PQ neurotoxicity increased the activity of the antioxidant transcription factor Nrf2 in cultured astrocytes, and PQ-induced dopaminergic cell death was attenuated in Nrf2-expressing midbrain cultures. In other studies, we found that extracts prepared from hibiscus, grape skin, or purple basil (but not plums) rescued defects in O2 consumption in neuronal cells treated with rotenone.

Tipularia discolor produces a single wintergreen leaf in autumn, which is drab brown in color during expansion. Upper (adaxial) surfaces of fully-expanded leaves may be green, purple-spotted, or solid purple, while lower (abaxial) surfaces are bright magenta. Our results showed that the same three cyanidin 3,7,3′-triglucosides, in similar concentrations and proportions, accounted for coloration in each of these cases, and that different colors result from differences in histological location of anthocyanins (i.e. abaxial/adaxial epidermis, mesophyll). Anthocyanins with 3,7,3′ linkage positions are rare in plants, occurring only within the orchid subfamily Epidendroideae, to which Tipularia belongs.

Broad sense heritability of the traits estimated in 100 tetraploid accessions, ranged from 20 to 90%, with most traits revealing moderate to high broad sense heritability (H2 > 40%), suggesting that strong genetic factors control these traits. Fruit size can be estimated as a proxy of fruit weight or volume and vice versa, and it was negatively correlated with content of most of phytochemicals evaluated here. However, size-independent variation for anthocyanin content and profile (e.g., acylated vs. non-acylated anthocyanin) exists in the tetraploid accessions and can be explored to identify other factors such as genes related to the biosynthetic pathway that control this trait. This result also suggests that metabolite concentrations and fruit size, to a certain degree can be improved simultaneously in breeding programs. Overall, the results of this study provide a framework to uncover the genetic basis of bioactive compounds and fruit quality traits and will be useful to advance blueberry-breeding programs focusing on integrating these traits.}, journal={Frontiers in Plant Science}, author={Mengist, M.F. and Grace, M.H. and Xiong, J. and Kay, C.D. and Bassil, N. and Hummer, K. and Ferruzzi, M.G. and Lila, M.A. and Iorizzo, M.}, year={2020} } @article{xiong_chan_rathinasabapathy_grace_komarnytsky_lila_2020, title={Enhanced stability of berry pomace polyphenols delivered in protein-polyphenol aggregate particles to an in vitro gastrointestinal digestion model}, volume={331}, url={http://www.scopus.com/inward/record.url?eid=2-s2.0-85086513528&partnerID=MN8TOARS}, DOI={10.1016/j.foodchem.2020.127279}, abstractNote={Stability of protein-polyphenol aggregate particles, created by complexing polyphenols from blueberry and muscadine grape pomaces with a rice-pea protein isolate blend, was evaluated in an in vitro gastrointestinal model.

Recently, we showed that bilirubin has protective effects in models of pancreatic islet transplantation, preventing cell death associated with islet stress and suppressing the release of damage-associated molecular patterns. Despite these promising therapeutic attributes, the natural bilirubin used in these research studies is animal-derived (porcine), making it unsuitable for clinical application. In the current study, we synthesized two bilirubin analogs that can be produced without the use of animal-derived products. Antioxidant activity for the analogs was measured using the ferric-reducing-ability-of-plasma (FRAP) and 2,2V-azinobis(3-ethylbenzothiazoline-6-sulfonate) (ABTS) assays. Dose-dependent cytotoxicity and cytoprotective effects were then demonstrated in isolated rat islets. Compound 1 showed similar antioxidant activity to natural bilirubin. Dose-dependent cytotoxicity was seen following treatment with Compound 1 and natural bilirubin at doses >40 μM, resulting in significantly increased cell death when compared to control islets ( P < 0.05) or islets treated with doses ≤20 μM ( P < 0.05). Following hypoxic challenge, islet cell death was reduced in islets treated with Compound 1 at 10 μM (17.27% ± 0.26%) compared to natural bilirubin at 10 μM (51.36% ± 0.71%; P < 0.0001) or 20 μM (59.02% ± 0.83%; P < 0.0001) and control islets (36.51% ± 0.44%; P < 0.0001).

Traditional use of Alaskan berry preparations in the treatment of skin wounds is recorded but has not been scientifically evaluated. Alaskan wild berries feature diverse phytochemical compositions that contain a variety of bioactive polyphenols exhibiting anti-inflammatory, antioxidant, and antimicrobial properties, making them ideal for wound healing interventions and natural anti-aging cosmeceutical formulations. Given increasing interest in identifying biologically active plant constituents for wound care and cosmeceutical applications, the objective of this study was to screen several wild berry species endemic to Alaska and the circumpolar Artic for wound healing and in the crude, polyphenol-enriched, and further fractionated extracts of: Empetrum nigrum (crowberry), Vaccinium uliginosum (bog blueberry), and V. vitis-idaea (low-bush cranberry or lingonberry). A cell migration assay with human dermal fibroblasts (HDFa) was performed to model promotion of wound closure, revealing that bog blueberry extract most actively promoted migration, whereas divergent effects observed with other berry extracts were related to compositional disparities. Lipopolysaccharide (LPS)-stimulated inflammatory response variables measured in RAW 264.7 macrophages [reactive oxygen species (ROS), NO production, prostaglandin-endoperoxide synthase 2 (COX-2), and inducible nitric oxide synthase (iNOS) expression] were suppressed by most extracts/fractions, but especially bog blueberry and proanthocyanidin (PAC) fractions. Wild berry germplasm contained abundant complex flavonoid structures such as PAC and anthocyanins (ANCs), associated with enhanced repair and inflammatory resolution in these models. Next, underlying mechanisms by which PACs and bioactive metabolites (B2 dimer and epicatechin) could influence wound repair and tissue regeneration were examined. PAC metabolites promoted scratch-wound closure and appeared to exert the highest impacts on early stages of wound healing through stimulating mitochondrial bioenergetics (basal respiration, ATP production, and maximum respiratory capacity) and upregulating expression of important extracellular matrix (ECM) proteins (integrin-ß1 and collagen type I α2 chain). Targeting cellular bioenergetics and integrin-mediated cell–ECM signaling with bioactives from Alaskan wild berries shows considerable therapeutic promise to treat chronic skin wounds and inflammatory skin disorders, as well as more generally to support regenerative healing responses and restore function in a variety of tissue and organ settings after injury or aging.}, number={SEP}, journal={FRONTIERS IN PHARMACOLOGY}, author={Esposito, Debora and Overall, John and Grace, Mary H. and Komarnytsky, Slavko and Lila, Mary Ann}, year={2019}, month={Sep} } @article{velde_esposito_grace_pirovani_lila_2019, title={Anti-inflammatory and wound healing properties of polyphenolic extracts from strawberry and blackberry fruits}, volume={121}, ISSN={["1873-7145"]}, url={http://dx.doi.org/10.1016/j.foodres.2018.11.059}, DOI={10.1016/j.foodres.2018.11.059}, abstractNote={The polyphenolic profiles by HPLC-TOF-MS of strawberry ‘San Andreas’ and blackberry ‘Black Satin’ crude extracts (CE) were analyzed.

The storage of samples in 70 kPa O2 + 20 kPa CO2 controlled microbiological decay and slightly affected soluble solids and pH values for 20 d at 5 °C. Moreover, vitamin C and proanthocyanidin contents of these samples were kept almost constant throughout the storage period. Samples in 90 kPa O2 + 10 kPa CO2 controlled microbiological decay for 12 d at 5 °C, soluble solids and pH values were slightly affected, and vitamin C and proanthocyanidin contents experienced up to 15% decrease during this period. However, anthocyanins underwent a substantial increase during the first 3–5 d of storage in these samples.

Thereafter, anthocyanins content decreased gradually or remained even higher than their initial values at 12 d. This behavior was associated with a physiological response to stress and was not seen for strawberries stored at 70 kPa O2 + 20 CO2, probably due to its higher CO2 concentration which was deleterious for anthocyanin stability.

Methods: Different chromatographic techniques for the aerial parts of Jacquemontia pentantha extract were used resulting in isolation of eight compounds. Their structures were elucidated by spectroscopic methods including 1HNMR, 13CNMR, EI/MS spectrometry and by comparing their data with those reported in the literature. The cytotoxicity was evaluated using MTT assay. The mode of action of the extract was predicted by using Enzyme-linked Immunosorbent Assay Kit for Tubulin beta (TUBb).

The basis for differences in coloration between individuals in this species is unknown. Because leaf purpling is often a sign of physiological stress, we hypothesized that adaxially purple and/or spotted individuals would exhibit reduced photosynthetic capacity compared to adaxially green individuals, and that adaxially purple tissues would exhibit symptoms of shade acclimation relative to adaxially green tissues (consistent with a photoprotective function of anthocyanin pigments). We made the following measurements on samples of the 3 morphotypes: photosynthetic response to light and intercellular CO2, monthly photosynthetic gas exchange and chlorophyll fluorescence, and quantification of foliar pigments (chlorophylls, xanthophylls, and anthocyanins). Inconsistent with both hypotheses, the 3 morphotypes did not differ in any of the parameters measured, except anthocyanin content. Furthermore, corms continued to produce leaves with the same pigment patterns in subsequent years, even when sunlight, fertilizer, and water were controlled for in a greenhouse setting.

Control plants were grown on Murashige and Skoog (MS) medium, acclimatized in the greenhouse and grown in the field. The volatile constituents were investigated by GC-MS.The total content of volatiles was affected by fertilizer treatments, and in vitro treatment with Ca2+ and KNO3; but PO43- and Mg2+ had no significant effect. The content was higher in the high-input fertilizer treatments (49.7 ± 9 mg/g DM) with 4 mM Ca2+, 60 mM KNO3 and 5 mM NH4+, than the low-input fertilizer (26.6 ± 9 mg/g DM), and the MS control (15.28 ± 2.7 mg/g DM; 3 mM Ca2+, 20 mM K+, 39 mM NO3-, 20 mM NH4+, 1.25 mM PO43-, and 1.5 mM Mg2+). The interaction of Ca2+ with KNO3 affected curcumenol isomer I and II, germacrone, isocurcumenol, and β-elemenone content. Increasing in vitro phosphate concentration to 6.25 mM increased ex vitro neocurdione and methenolone contents.These results show that minerals in the in vitro bioreactor medium during rhizome development affected biosynthesis of turmeric volatile components after transfer to the greenhouse six months later. The multi-factor design identified 1) nutrient regulation of specific components within unique phytochemical profile for Curcuma longa L. clone 35-1 and 2) the varied phytochemical profiles were maintained with integrity during the greenhouse growth in high fertility conditions.}, number={1}, journal={BMC Plant Biology}, author={El-Hawaz, R.F. and Grace, Mary H and Janbey, A. and Lila, Mary Ann and Adelberg, J.W.}, year={2018}, month={Dec} } @article{el-hawaz_grace_janbey_lila_adelberg_2018, title={In vitro mineral nutrition of Curcuma longa L. affects production of volatile compounds in rhizomes after transfer to the greenhouse}, volume={18}, journal={BMC Plant Biology}, author={El-Hawaz, R.

The walkers (flavonoid, placebo groups) were randomized to either sit or walk briskly on treadmills for 45 min (thus, four groups: placebo–sit, placebo–walk, flavonoid–sit, flavonoid–walk). A comparator group of runners (n = 19) ingested a double flavonoid dose for two weeks (658 mg/day) and ran for 2.5 h (69.2 ± 1.2% VO2max). Four blood samples were collected (pre- and post-supplementation, immediately post- and 24 h post-exercise/rest). Of the 76 metabolites detected in this targeted analysis, 15 increased after the 2.5 h run, and when grouped were also elevated post-exercise (versus placebo–sit) for the placebo– and flavonoid–walking groups (p < 0.05). A secondary analysis showed that pre-study plasma concentrations of gut-derived phenolics in the runners were 40% higher compared to walkers (p = 0.031). These data indicate that acute exercise bouts (brisk walking, intensive running) are linked to an increased translocation of gut-derived phenolics into circulation, an effect that is amplified when combined with a two-week period of increased flavonoid intake or chronic training as a runner.}, number={11}, journal={Nutrients}, author={Nieman, David C. and Kay, Colin and Rathore, Atul S and Grace, Mary H. and Strauch, Renee C. and Stephan, Ella H. and Sakaguchi, Camila A. and Lila, Mary Ann}, year={2018}, month={Nov} } @article{ inter- and intra-seasonal changes in anthocyanin accumulation and global metabolite profiling of six blueberry genotypes_2017, DOI={doi.org/10.1016/j.jfca.2017.02.019}, abstractNote={Anthocyanin content in six blueberry genotypes was evaluated across two harvest seasons.

Anthocyanins have generally been considered to have notoriously poor bioavailability, based on the very low levels typically detected in routine human blood draws after ingestion. Although some investigations have assessed anthocyanin bioavailability solely based on the measurement of parent anthocyanins or phenolic acid breakdown products, more recent research has increasingly revealed the presence, qualitative diversity, relatively high concentrations, and tenacity of molecular intermediates of anthocyanins that retain the unique flavonoid C6-C3-C6 backbone structure.

Anthocyanins, because of their health benefits, are the major focus of interest in maqui fruit. For this study, we examined anthocyanin and phenolic content of maqui fruits from individuals that belonged to four geographical areas in Chile, and used DNA marker analysis to examine the genetic variability of maqui populations that had distinctly different fruit anthocyanin content. RESULTS Twelve primers generated a total of 145 polymorphic inter simple sequence repeat-polymerase chain reaction (ISSR-PCR) bands. ISSR-PCR showed different banding patterns for the individuals evaluated, confirming that maqui populations belonged to different genotypes. Maqui fruit from four different geographical regions during two consecutive growing seasons showed high total anthocyanin (6.6-15.0 g cy-3-glu kg⁻¹ fresh weight (FW)) and phenolic (10.7-20.5 g GAE kg⁻¹ FW) contents and different anthocyanin profiles.

Objective: This study evaluates the in vitro leishmanicidal and cytotoxicity activities of isolated compounds based on a bioassay-guided fractionation approach. Materials and methods: Defatted aerial parts of E. foetidum were subjected to extraction with methanol followed by partitioning with n-hexane, ethyl acetate and 50% methanol. Then, the first two fractions were subsequently fractionated by column chromatography and HPLC. Compound identity was confirmed by mass spectrometry and NMR spectroscopy. Leishmania tarentolae (promastigotes) and L. donovani (amastigotes) were used as testing parasites. L6 rat myoblasts were used for cytotoxicity. All extracts and fractions were tested at 20 μg/mL. Results: The initial methanol extract showed 20% growth inhibition of L. tarentolae. Then, the n-hexane and ethyl acetate fractions were also active showing approximately 40% growth inhibition. From these two fractions, the following compounds were isolated: lasidiol p-methoxybenzoate (1), a daucane sesquiterpene; and 4-hydroxy-1,1,5-trimethyl-2-formyl-cyclohexadien-(2,5)-[α-acetoxymethyl-cis-crotonate] (2), a terpene aldehyde ester derivative. Compound 1 inhibited the growth of both L. tarentolae and L. donovani with IC50 values of 14.33 and 7.84 μM, respectively; and showed no cytotoxicity (IC50 > 50 μM).

The compound recoveries ranged from 94.2 to 97.5 ± 5.3% when samples were spiked with commercial standards prior to extraction. Eighteen anthocyanins and 4 phenolic acids were quantified in frozen and freeze-dried fruits. Large variations for individual and total anthocyanins, ranging from 201.4 to 402.8 mg/100 g, were assayed in frozen fruits. The total phenolic acid content ranged from 23.6 to 61.7 mg/100 g in frozen fruits. Across all genotypes, freeze-drying resulted in minor reductions in anthocyanin concentration (3.9%) compared to anthocyanins in frozen fruits.

However, when processed by techniques such as pressing, canning, concentrating, or drying, a number of these natural components may be compromised or inactivated due to physical separation, thermal degradation, or oxidation. Fresh cranberries were compared to freeze‐dried berries and individual fruit tissues (skin and peeled fruit). Products examined included cranberry juices (commercial and prepared from concentrate), cranberry sauces (commercial and homemade), and sweetened‐dried cranberries (commercial). Freeze‐drying resulted in no detectable losses of anthocyanins or proanthocyanidins from cranberry fruits. Anthocyanins were localized in the skin. Proanthocyanins were higher in the skin than in the flesh, with the exception of procyanidin A‐2 dimer which was concentrated in the flesh. Anthocyanins were significantly higher in not‐from‐concentrate juice than in reconstituted juice from concentrate (8.3 mg and 4.2 mg/100 mL, respectively). Similarly, proanthocyanidins were markedly higher in not‐from‐concentrate juice compared to juice from concentrate (23.0 mg and 8.9 mg/100 mL, respectively). Homemade sauce contained far higher anthocyanins and proanthocyanidins (15.9 and 87.9 mg/100 g, respectively) than canned sauces processed with whole berries (9.6 and 54.4 mg/100 g, respectively) or jelled‐type (1.1 and 16 mg/100 g, respectively). Sweetened‐dried cranberries were quite low in anthocyanins (7.9 mg/100 g), but they still retained considerable proanthocyanidins (64.2 mg/100 g). Commercially processed products contained significantly lower levels of polyphenols as compared to fresh and home‐processed preparations.

Major N-alkylamides in S. acmella were isolated from a methanolic crude extract of flowers by CPC with the solvent system heptanes-ethyl acetate-methanol-water (3:2:3:2, v/v/v/v). Four N-alkylamides were purified and the structures were illustrated by electrospray ionization-ion trap-time of flight-mass spectrometry (ESI-IT-TOF-MS), ¹H nuclear magnetic resonance (¹H NMR) and ¹³C nuclear magnetic resonance (¹³C NMR). The CPC fractions, which contained natural mixtures of phytochemicals, demonstrated significantly higher antiplasmodial activity compared to corresponding purified N-alkylamides, thus suggesting that interactions between these N-alkylamides may potentiate antiplasmodial bioactivity.}, number={21}, journal={Journal of Chromatography B}, publisher={Elsevier BV}, author={Mbeunkui, Flaubert and Grace, Mary H. and Lategan, Carmen and Smith, Peter J. and Raskin, Ilya and Lila, Mary Ann}, year={2011}, month={Jul}, pages={1886–1892} } @inproceedings{variation of resveratrol and anthocyanins contents in blueberry species and cultivars and their implications for human health. berry health benifits symposium, westlake, ca ,_2011, year={2011} } @article{grace_lategan_mbeunkui_graziose_smith_raskin_lila_2010, title={Antiplasmodial and cytotoxic activities of drimane sesquiterpenes from Canella winterana}, volume={5}, url={http://www.scopus.com/inward/record.url?eid=2-s2.0-78751538177&partnerID=MN8TOARS}, number={12}, journal={Natural Product Communications}, author={Grace, M.H. and Lategan, C. and Mbeunkui, F. and Graziose, R. and Smith, P.J. and Raskin, I. and Lila, M.A.}, year={2010}, pages={1869–1872} } @article{mun_grannan_lachcik_rogers_yousef_grace_janle_wu_simon_weaver_et al._2010, title={Tracking deposition of a 14C-radiolabeled kudzu hairy root-derived isoflavone-rich fraction into bone}, volume={235}, url={http://www.scopus.com/inward/record.url?eid=2-s2.0-77957828954&partnerID=MN8TOARS}, DOI={10.1258/ebm.2010.010134}, abstractNote={ Hairy roots were induced in four genotypes from three kudzu species ( Pueraria montana var. lobata, P. lobata and P. phaseoloides) in vitro using Agrobacterium rhizogenes to stimulate rapid secondary metabolite synthesis. Hairy roots from P. montana var. lobata (United States Department of Agriculture no. PI 434246) yielded the highest puerarin and total isoflavone content and the greatest new biomass per growth cycle among the genotypes evaluated. Hairy roots from this genotype were selected for radiolabeling using 14C-sucrose as a carbon source. Isoflavones from radiolabeled kudzu hairy root cultures were extracted with 80% methanol, partitioned by solvent extraction, and then subfractionated by Sephadex LH-20 gel filtration. Radiolabeled isoflavones were isolated in a highly enriched fraction, which contained predominantly puerarin, daidzin and malonyl-daidzin and had an average radioactivity of 8.614 MBq/g (232.8 μCi/g) dry fraction. The 14C-radiolabeled, isoflavone-rich fraction was orally administered at a dose of 60 mg/kg body weight to male Sprague–Dawley rats implanted with a jugular catheter, a subcutaneous ultrafiltrate probe and a brain microdialysate probe. Serum, interstitial fluid, brain microdialysate, urine and feces were collected using a Culex® Automated Blood Collection System for 24 h. At the end of this period, rats were sacrificed and major tissues were collected. Analysis by a scintillation counter confirmed that a bolus dose of 14C-radiolabeled, isoflavone-rich kudzu fraction reached bone tissues, which accumulated 0.011%, 0.09% and 0.003% of the administered dose in femur, tibia and vertebrae, respectively. Femurs extracted with 80% methanol were analyzed by high-performance liquid chromatography with electrospray ionization–mass spectrometry and were found to contain trace quantities of puerarin, daidzein and puerarin glucuronide. This study demonstrates that kudzu isoflavones and metabolites are capable of reaching bone tissues, where they may contribute to the prevention of osteoporosis and the promotion of bone health. }, number={10}, journal={Experimental Biology and Medicine}, author={Mun, J.G. and Grannan, M.D. and Lachcik, P.J. and Rogers, R.B. and Yousef, G.G. and Grace, M.H. and Janle, E.M. and Wu, Q.L. and Simon, J.E. and Weaver, C.M. and et al.}, year={2010}, pages={1224–1235} } @article{grace_wilson_kandil_dimitriadis_coates_2009, title={Characteristic flavonoids from Acacia burkittii and A. acuminata heartwoods and their differential cytotoxicity to normal and leukemia cells}, volume={4}, url={http://www.scopus.com/inward/record.url?eid=2-s2.0-66849101227&partnerID=MN8TOARS}, number={1}, journal={Natural Product Communications}, author={Grace, M.H. and Wilson, G.R. and Kandil, F.E. and Dimitriadis, E. and Coates, R.M.}, year={2009}, pages={69–76} } @article{grace_ribnicky_kuhn_poulev_logendra_yousef_raskin_lila_2009, title={Hypoglycemic activity of a novel anthocyanin-rich formulation from lowbush blueberry, Vaccinium angustifolium Aiton}, volume={16}, ISSN={0944-7113}, url={http://dx.doi.org/10.1016/j.phymed.2009.02.018}, DOI={10.1016/j.phymed.2009.02.018}, abstractNote={Blueberry fruits are known as a rich source of anthocyanin components. In this study we demonstrate that anthocyanins from blueberry have the potency to alleviate symptoms of hyperglycemia in diabetic C57b1/6J mice. The anti-diabetic activity of different anthocyanin-related extracts was evaluated using the pharmaceutically acceptable self-microemulsifying drug delivery system: Labrasol. Treatment by gavage (500 mg/kg body wt) with a phenolic-rich extract and an anthocyanin-enriched fraction formulated with Labrasol lowered elevated blood glucose levels by 33 and 51%, respectively. The hypoglycemic activities of these formulae were comparable to that of the known anti-diabetic drug metformin (27% at 300 mg/kg). The extracts were not significantly hypoglycemic when administered without Labrasol, demonstrating its bio-enhancing effect, most likely due to increasing the bioavailability of the administered preparations. The phenolic-rich extract contained 287.0+/-9.7 mg/g anthocyanins, while the anthocyanin-enriched fraction contained 595+/-20.0 mg/g (cyanidin-3-glucoside equivalents), as measured by HPLC and pH differential analysis methods. The greater hypoglycemic activity of the anthocyanin-enriched fraction compared to the initial phenolic-rich extract suggested that the activity was due to the anthocyanin components.

TP fractions 2 through 6 were recombined and further subfractionated using silica gel (SG) into 22 subfractions. Crude extract, TP fractions, and SG subfractions were screened in a L1210 murine leukemia cell assay and a human DNA catalytic topoisomerase II assay in order to gauge the cancer chemopreventive potential of each genotype. SG subfraction 6 from the cultivated genotype showed >90% inhibitory activity at 25 μg/mL, and a similar fraction from the wild genotype showed >95% inhibitory activity to L1210 leukemia cells at a concentration of 50 μg/mL. On the basis of topoisomerase inhibition, it can be concluded that all TP fractions of the wild genotype act as catalytic inhibitors. Similar anthocyanins and oligomeric proanthocyanidins were identified from both Aronia genotypes; however, HPLC‐ESI‐MS spectra indicated higher flavonoid concentration in the wild Aronia and a predominance (up to 67%) of nonphenolic compounds in the berries from the cultivated genotype.

Chemical similarities among the three species were observed; however, each species displayed differences in phytochemical constituents. R. heterodonta contained a newly detected phenylethanoid glycoside, heterodontoside, in addition to the known compounds tyrosol, viridoside, salidroside, and rhodiocyanoside A. Both R. heterodonta and R. rosea contained phenylethanoid/propanoid compounds that were not detected in R. semenovii. For R. semenovii, the cyanogenic glucosides rhodiocyanoside A and lotaustralin were detected.
