Abstract
Bioactivity guided separation of Reinwardtiodendron cinereum barks methanol extract led to the isolation of two new onocerane triterpenoids, reinereins A and B (1 and 2), together with three known onocerane triterpenoids. Their structures were elucidated on the basis of NMR spectroscopic data. In vitro cytotoxic activities of the isolated compounds against several type of cancer cells were evaluated.
