Two new triterpene esters from the twigs of Brachylaena ramiflora from the Madagascar rainforest. Journal of natural products, 2002, Volume: 65, Issue:8 Bioassay-guided fractionation of a CH(2)Cl(2)/MeOH extract of the small twigs of Brachylaena ramiflora var. ramiflora resulted in the isolation of the two new triterpene esters 1 and 2 and five known triterpenoids, alpha-amyrin palmitate (3), beta-amyrin palmitate (4), beta-amyrin acetate (5), lupeyl acetate (6), and lupeol (7). The structures of the two new compounds were established as kairatenyl palmitate (1) and hopenyl palmitate (2) on the basis of 1D and 2D NMR spectroscopic data interpretation and chemical conversions. All the isolated compounds showed weak cytotoxicity against the A2780 human ovarian cancer cell line.
