Extraction and Characterization of Proanthocyanidins from Grape Seeds
Grape seed contains many polyphenolic compounds that have potential health-promoting benefits. Among these compounds are proanthocyanidins, also known as condensed tannins, which is a class of flavanols. The basic structural building blocks of flavanols are polyhydroxyflavan-3-ol units linked together by C-C bonds. They are widely distributed in plants but grape seed has very high contents. Thi...
متن کاملProtective effect of red grape seeds proanthocyanidins against induction of diabetes by alloxan in rats.
It has been documented that impaired homeostasis in diabetes mellitus is associated with increased production of reactive oxygen species and depletion of the antioxidant defense systems. Natural grape seed proanthocyanidins (GSP) are potent free radical scavengers and hence provide significant protection against oxidative stress. Accordingly, the present study focused on investigating the possi...
متن کاملProtective Effect of Grape Seeds Proanthocyanidins against Naphthalene-induced Hepatotoxicity in Rats
Oxidative stress with subsequent production of reactive oxygen species has been postulated as one of the mechanisms of naphthalene toxicity. In the present study, the effect of oral administration of the natural antioxidant and free radical scavenger, proanthocyanidins present in grape seeds (GSP, 10 or 50 mg kg, p.o.), has been investigated in rats following the concomitant administration of n...
متن کاملOligomeric proanthocyanidins from grape seeds effectively inhibit ultraviolet-induced melanogenesis of human melanocytes in vitro.
The oligomeric proanthocyanidins (OPCs) from grape seeds are expected to be novel and potent anti-oxidants that more effectively protect skin cells against oxidative stress. UV-induced oxidative stress is considered to promote melanogenesis and serious skin damage. However, the effect of OPCs on UV-induced melanogenesis is still unknown. To investigate the role of OPCs on melanogenesis of human...
متن کاملSecondary metabolites in durian seeds: oligomeric proanthocyanidins.
Ethanolic extract of durian seeds was fractionated by reverse phase flash column chromatography and the fractions characterized by electrospray ionization mass spectroscopy. Among a few unknown compounds collected, oligomeric proanthocyanidins (OPCs) were found to be one of the main compounds. Based on this result, the OPCs were purified the first time from the durian seeds using standard proce...
