In this study, isolation of antioxidative compounds was performed for development of anti-oxidizing agent. $CHCl_{3}$, $H_{2}O$, 30%, 60% MeOH, MeOH fractions were examined antioxidative activity by DPPH method, TBARS assay, and SOD like activity. It was revealed that 30%, 60% MeOH fractions had significant antioxidative activity. From 30%, 60% MeOH fraction, nine compounds were isolated and elucidated kaempferol $3-O-{alpha}-L-rhamnopyranosyl$ $(1{ ightarrow}6)-{eta}-D-glucopyranoside$ (1), quercetin $7-O-{eta}-D-glucopyranoside$ (II), quercetin $3-O-{alpha}-L-rhamnopyranosyl$ $(1{ ightarrow}6)$ ${eta}-D-glucopyranoside(rutin)$ (III), 6-hydroxykaempferol $3-O-{eta}-D-glucopyranoside$ (lV), kaempferol $3-O-{eta}-D-glucopyranosyl$ $(1{ ightarrow}2)$ ${eta}-D-glucopyranoside$ (V), kaempferol $3-O-{eta}-D-glucopyranoside$ (VI), luteolin (VII), quercetin $3-O-{eta}-D-glucopyranoside$ (VIII), apigenin $7-O-{eta}-D-glucuronopyranoside$ (IX) through physicochemical data and spectroscopic methods (Negative FAB-MS, $^1H-NMR$, $^{13}C-NMR$). Entirely, all compounds had similar antioxidative activity, but more OH group had more antioxidative activity.
