Three chromanone acids, blancoic acid (1), isoblancoic acid (2) and chapelieric acid (3), were isolated from the bark of Calophyllum dongnaiense Pierre collected in Dong Nai Province. Their structures were elucidated using spectroscopic techniques (1-D and 2-D NMR, UV, IR and MS) as well as chemical methods. Cytotoxicity of compounds 1-3 and their 5-O-acetylated and methylated derivatives against Hela cell line was examined.
