Abstract
The crude ethanol extract from the leaves of Dendroponax cf. querceti (Araliaceae) from Monteverde, Costa Rica, exhibits cytotoxic activity against Hep-GZ, A-431, and H-411E tumor cell lines. The active compone nt has been isolated by activity-directed separation and identified by H-1-and C-13-NMR spectroscopy as the triterpene lupeol. The mechanism of cytotoxic activity of lupeol has been determined to be inhibition of topoisomerase II.
