Abstract
Three new compounds, actinidione (1), 3β,29-dihydroxylup-20(30)-en-28-al (2) and 3β-O-trans-caffeoyl-29-hydroxybetulin (3), along with twenty known compounds (4 - 23), were isolated from the leaves and twigs of Clematoclethra actinidioides Maxim. Their structures were determined by analysis of spectral data or comparison with authentic samples. Compounds 1, 2 and 3 exhibited cytotoxicity against Lu-06, N-04 and Bre-04 cell lines with GI50 values of 15.02 - 41.64 μg/mL.
