영문 초록

Two ellagitannins, pedunculagin and 2,3-(S)-Hexahydroxydiphenoyl (HHDP)-D-glucose and three condensed tannins, (+)-catechin, (-)-epicatechin and procyanidin B-4 which were isolated from Rubus coreanum were evaluated for their antioxidative effects with 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical and lipid peroxidation generation system mediated by addition of H202 to rat liver homogenate (TBARS). The ellagitannins, 2,3-(S)-HHDP-D-glucose and pedunculagin, showed more potent antioxidative activities by DPPH and TBARS than condensed tannins.
