Abstract

The interest of oligomeric proanthocyanidins(OPCs) as therapeutic agents against diseases involving radical damage is growing. Proanthocyanidins are a class of polyphenolic compounds in several plant species and are oligomers of flavan-3-ol monomer units. Polyphenols in green and black tea, grape seeds, grapes and wine have raised much attention but mountain grape seed has not been investigated intensively up to now This study investigated the total OPCs contents and the total antioxidant activity of mountain grape seeds. Total antioxidant activity using DPPH method was employed and OPCs contents were determined by means of the UV-VIS spectrophotometer. The total OPCs yield of mountain grape seeds was about 1.45 % and total antioxidant activity was 15.8 ${\mu}g/m{\ell}$.
