FWB: fresh weight basis; DWB: dry weight basis; EPB: extracted powder basis. polyphenol content, expressed in milligrams of gallic acid equivalents per gram. flavonoids content, expressed in milligrams of rutin equivalents per gram. oligomeric proanthocyanidins content, expressed in milligrams of grape seed extract equivalents per gram. Sample 1: the crude power extracted with ethanol-water (7 : 3, v/v). Sample 2: the power reextracted from Sample 1 with ethyl acetate. Sample 3: the power reextracted from Sample 1 with n-hexane. Sample 4: the power reextracted from Sample 1 with ether. Sample 5: the power reextracted from Sample 1 with methylene dichloride.
