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. Collectively, these findings suggest that extracts enriched with certain combinations of ANC, PAC, stilbenes, and other polyphenols could potentially slow neurodegeneration in the brains of individuals exposed to PQ or rotenone by activating cellular antioxidant mechanisms and/or alleviating mitochondrial dysfunction.}, number={7}, journal={ANTIOXIDANTS}, author={Tambe, Mitali A. and Jacquet, Aurelie de Rus and Strathearn, Katherine E. and Hensel, Jennifer A. and Colon, Bryce D. and Chandran, Aswathy and Yousef, Gad G. and Grace, Mary H. and Ferruzzi, Mario G. and Wu, Qingli and et al.}, year={2023}, month={Jul} }

Maqui (Aristotelia chilensis) is a Chilean species which produces small berries that are collected from the wild. 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.


CONCLUSION
Three maqui genotypes exhibited significantly higher anthocyanin content than the others, as measured by pH differential method and high-performance liquid chromatography-mass spectrometry. Significant genetic diversity was noted within each ecological population. ISSR-PCR analysis provided a fingerprinting approach applicable for differentiation of maqui genotypes.}, number={13}, journal={JOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE}, author={Fredes, Carolina and Yousef, Gad G. and Robert, Paz and Grace, Mary H. and Lila, Mary Ann and Gomez, Miguel and Gebauer, Marlene and Montenegro, Gloria}, year={2014}, month={Oct}, pages={2639–2648} }

For berries endemic to the wind-battered open plains of the Dakotas, the arctic tundra of Alaska, exposed elevations in the Andean Mountains or the nutrient-starved lava flows of Pacific Islands, certain stresses can be taken to extreme limits, triggering deposition of potent phytochemical mixtures within berry fruits. The unique and sometimes dramatic phytochemical melange not only protects the host plant from insult, but also offers broad-spectrum health benefits to the animals (including humans) that consume these berries. Traditional diets in many native cultures have featured wild game, seafood, and a plethora of these wild berry species including salmonberries, mossberries, maquiberry, buffaloberry, blue huckleberries and bog blueberries. In recent years, just as native communities have shifted towards more Western diets and away from traditions, the incidence of diabetes and obesity has risen.

Curing and storage for up to 8 months did not significantly affect total phenolic content in Covington, Yellow Covington, and NC07-847, however for NCPUR06-020, a purple-fleshed selection, total phenolic content declined mainly due to anthocyanin degradation during storage. Covington had the highest carotenoid content at harvest time (281.9 μg/g DM), followed by NC07-847 (26.2 μg/g DM), and after 8 months, total carotenoids had increased by 25% and 50%, respectively. Antioxidant activity gradually declined during storage, and freshly harvested sweetpotatoes also demonstrated higher anti-inflammatory capacity as gauged by inhibition of lipopolysaccharide-induced reactive oxygen species (ROS) in SH-SY5Y cells.

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. Anthocyanins were more sensitive to degradation than proanthocyanidins.Practical Application:  As cranberry juices and other products are increasingly consumed for their recognized health benefits (including prophylaxis against urinary tract infection), it is relevant to consider how various degrees of commercial and home processing can alter innate levels of the biologically active flavonoids (especially anthocyanins and proanthocyanidins) characteristic to the intact fruits.}, number={8}, journal={JOURNAL OF FOOD SCIENCE}, author={Grace, Mary H. and Massey, Aaron R. and Mbeunkui, Flaubert and Yousef, Gad G. and Lila, Mary Ann}, year={2012}, month={Aug}, pages={H176–H183} }

The health benefits of blackcurrant have generally been credited to its high anthocyanin content; however, the therapeutic properties of other minor flavonoids constituents have not yet been investigated due the difficulties related to their isolation. Multiple steps of high‐performance counter‐current chromatography in combination with ESI tandem mass spectrometry (MSn) were successfully used for the preparative isolation of flavonols from blackcurrant extract, to study their electrospray ionization mass spectrometry fragmentation behavior. Seven flavonols, namely myricetin‐3‐O‐rutinoside (145.5 mg), myricetin‐3‐O‐hexoside (79.7 mg), myricetin‐3‐O‐(6″‐malonyl)‐glucoside (17.4 mg), kaempferol‐3‐O‐glucoside (20.5 mg), quercetin‐3‐O‐rutinoside (55.1 mg), quercetin‐3‐O‐hexoside (25.8 mg), and myricetin (129.1 mg) have been successfully isolated and their multistage MSn data were used for detailed structure characterization. The results of these experiments demonstrated that high‐performance counter‐current chromatography along with ESI‐MSn is a sensitive, selective, and effective technology for isolation and characterization of minor constituents from a complex mixture.}, number={13}, journal={JOURNAL OF SEPARATION SCIENCE}, author={Mbeunkui, Flaubert and Grace, Mary H. and Yousef, Gad G. and Lila, Mary Ann}, year={2012}, month={Jul}, pages={1682–1689} }

Six genotypes, including WB-3, WB-7, WB-10, and WB-11 (all wild blackberry types), Tupy (a commercial cultivar), and UM-601 (a cultivated breeding line), were selected and profiled for anthocyanins and proanthocyanidins by separating extracts over Amberlite XAD-7 resin and Sephadex LH-20 columns. Subsequent high-performance liquid chromatography (HPLC) and liquid chromatography-electrospray ionization-mass spectrometry (LC-ESI-MS) analyses revealed that the major anthocyanin for all genotypes was cyanidin 3-O-glucoside. The proanthocyanidins (condensed tannins) were present in mono- to hexamer forms. Also, hydrolyzable tannins, ellagitannins, were characterized in the blackberry fruits. The average anthocyanin concentration in Sephadex LH-20 fractions was 49.2 mg/g in the commercial cultivar Tupy, while in the wild genotypes and the breeding line, the range was 361.3-494.9 mg/g (cyanidin 3-O-glucoside equivalent). The proanthocyanidin concentration varied widely among wild genotypes (417.5-1343.6 mg/g, catechin equivalent). This study demonstrated that the use of Amberlite XAD-7 followed by Sephadex LH-20 chromatography, with subsequent HPLC and LC-ESI-MS analyses, was able to effectively separate and characterize the diverse polyphenolics in blackberry genotypes. These results suggest that recommendations for dietary intake of blackberries for human health benefits need to take into account the source, because of the wide inherent variation in bioactive polyphenolic content in different blackberry genotypes.}, number={12}, journal={JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY}, author={Cuevas-Rodriguez, Edith O. and Yousef, Gad G. and Garcia-Saucedo, Pedro A. and Lopez-Medina, Jose and Paredes-Lopez, Octavio and Lila, Mary Ann}, year={2010}, month={Jun}, pages={7458–7464} }

At 50 microM [cyanidin-3-O-glucoside (C3G) or catechin equivalent], most fractions significantly (P<0.05) inhibited all markers. The anthocyanin-rich fraction from WB-10 and the proanthocyanidin-rich fraction from UM-601 exhibited the highest NO inhibitory activities (IC50=16.1 and 15.1 microM, respectively). Proanthocyanidin-rich fractions from the wild WB-10 showed the highest inhibition of iNOS expression (IC50=8.3 microM). Polyphenolic-rich fractions from WB-7 and UM-601 were potent inhibitors of COX-2 expression (IC50=19.1 and 19.3 microM C3G equivalent, respectively). For most of the extracts, antioxidant capacity was significantly correlated with NO inhibition.
