This study was carried out to investigate the antioxidative activities of domestic plants grown in the area of Kangwon-do province. Through the examination of methanol extracts from 15 plants for radical scavenging effects using DPPH method, the extracts from Pinus densiflora Sieb. et Zucc. And Euphorbia humifusa Willd. Showed strong antioxidative activity. Because of its highest antioxidative activity among 15 domestic plants, radical scavenging effects of four different extract compartments from leaves of P.densiflora, n-Hexane, EtOAc, BuOH and $H_2O$ extracts. Were examined by DPPH method. Antioxidative activities of EtOAc and BuOH extracts were similar or even higher than that of natural (tocopherol) or synthetic antioBfdants (BHA) , suggesting that major fraction for the antioxidative activity of P. densiflora was the EtOAc and BuOH extract compartments.
