Abstract:
Six coumarins have been isolated from the fruits and the stem bark of Calophyllum dispar (Clusiaceae). The structures of these minor components were established by means of spectroscopic analysis, including extensive 2D NMR studies. Some of these coumarins exhibited a significant cytotoxic activity against KB cells.
