摘要
Chemical investigation of the stem bark and leaves of Putranjiva roxburghii has resulted in the isolation of a new ellagic acid glycoside (5) along with four saponins (1-4). The structures of the isolated compounds were established by detailed spectral analysis. Incidentally putranoside-A methyl ester (4) has been isolated for the first time from this species and the saponins (1-4) exhibited potent DNA topoisomerase IB inhibitory activity.
