Objectives : This study was performed to investigate the antioxidant activities of isolated compounds from the shoot of Aralia elata. Methods : The methanol extract from the shoot of Aralia elata was fractionated into ethyl acetate, n-BuOH and $H_2O$ layers through solvent fractionation. Repeated silica gel, ODS column chromatography of n-BuOH layer afforded four flavonol glycosides. Their antioxidant activity was determined by measuring free radical scavenging activity by DPPH, ABTS and superoxide dismutase (SOD) like activity assay. Results : They were identified as quercetin 3,7-di-O-$alpha$-rhamnopyranoside (1), quercetin 3-O-$eta$-D-galactoside-7-O-$alpha$-L-rhamnoside (2), kaempferol 3-O-$eta$-glucosyl($1{ ightarrow}2$)-$alpha$-rhamnoside-7-O-$alpha$-rhamnoside (3) and quercetin 3-O-$eta$-glucosyl($1{ ightarrow}2$)-$alpha$-rhamnoside-7-O-$eta$-rhamnoside (4) on the basis of spectroscopic data. The result showed that 1 is the most active compound in the DPPH and ABTS radical scavenging test. Conclusions : Isolated Compounds from the shoot of Aralia elata showed anti-oxidative effect.
