Polygoni Radix (Polygonaceae) has been used as renal disorder, hematopoietic, menstrual irregularity and anti-aging in Korean folk medicine. Specially aerial parts has been used for insomnia and sedative agent. In order to investigate the efficacy of antioxidant activity on these aerial parts, the bio-activity guided fraction and isolation of physiologically active substance were performed. H2O, 30%, 60%, 100% MeOH were examined antioxidant activity by DPPH method. It was revealed that 30%, 60% MeOH fractions have significantly antioxidant activity. From 60% MeOH fraction, six known flavonoid glycosides (quercetin, quercetin 3-O-β-D-galactopyranosyl-4'-O-glucopyranoside-3'-methylether, quercetin 3-O-α-L-rhamnopyranoside, quercetin 3-O-α-L-rhamnophyrano side-4'-methylether, quercetin 3-O-β-D-galactopyranoside, quercetin 3-O-β-D-glucopyranoside) and 3,4-dihydrocinnamic acid were isolated. To investigated the antioxidant activities of each compounds, we measured radical scavening activity with DPPH method and anti-lipid peroxidative efficacy on low density lipo-protein(LDL) with TBARS assay and anti-acetylcholinestrase activity with Ellman's Test. Four compounds (Ⅱ,Ⅳ,Ⅵ,Ⅷ) of quercetin glycosides showed significant activity.

In a pattern analysis of GC-MS of 21 Leonuri herba samples harvested in China and Korea, characteristic differences were observed between Chinese and Korean samples. specifically, Leonuri herba form Hanllasan showed unusual retention time. Rutin was employed as a standard compound of Leonuri herba. All samples had 0.32${\pm}$0.18(%) rutin contents in average, but Korean samples had more rutin than Chinese one, especially the sample from Hanllasan of Jeju showed high-est rutin content (3.2%). In rutin contents of seasonal variation, there were more rutin contents in after blooming, 2years aged Leonuri herba than before.
