Abstract: In this study, ethanol (50 and 100%), methanol (70 and 100%), acetone (70 and 100%), chloroform 100% and water extract of grape seeds were evaluated for their antioxidant and antimicrobial activities. Extraction yield of grape seeds ranged from 6.0 to 14.50% depending on organic solvent type. Grape seed methanol 70% and ethanol 50% extract had significantly higher total phenolic (9.501 and 8.949 mg gallic acid/g), total flavonoids (6.707 and 6.398 mg quercetin /g) and antioxidant activity (702.37 and 636.50 µMolTrolox eq/gm), respectively than other grape seed extracts. While, grape seeds water extract showed the lowest total phenolic, flavonoids compounds and antioxidants activity. Twenty one phenolic and nine flavonoid compounds were identified by HPLC technique in each one of grape seed extracts
