초록

Cephalotaxus koreana Nakai is an endemic species in Korea. The EtOH extract of leaf and branch from the plant showed potent antitumor activity in Teruhiro's method. The tumor volume inhibition ratio value is 25.2% with 20mg/kg in the BDF1 mouse injected LLC cell. We isolated one flavone, sciadopitysin (1), two flavone O-glycosides, quercetin 3-O-${\beta}$-D-glucuronide 6"-ethyl ester (2), apigenin 7-neohesperidoside (3) in comparison with literatures data. Compounds 1-3 showed stronger antitumor activity than Taxol used as positive control. The inhibition ratio values of compounds 1-3 is 34.9, 31.6, 34.0%, respectively, and Taxol is 27.0 % compared with control group.
