Popis: Chromatographic fractionation of the cytotoxic n -hexane extract of Hopea odorata Roxb. leaves led to the isolation of eight lupane triterpenes, which constitutes the first report of lupane-type triterpenes from this plant source. Furthermore, 3,30-dioxolup-20(29)-en-28-oic acid ( 6 ) was isolated for the first time from a natural source. Their structures were determined on the basis of spectroscopic methods, including 2D NMR analysis, and by comparison of their spectral data with literature values. Complete NMR assignments of the 1 H and 13 C NMR data were achieved for all compounds. Finally, the cytotoxic activities of the isolated compounds against four human cell lines (PC3, MDA-MB-231, HT-29 and HCT116) was also reported.
