New Coumarins and Triterpenes from Calophyllum inophyllum

Four new coumarins, 1 – 4 , and two new triterpenes, 5 and 6 , along with nine known compounds have been identified from the leaves of Calophyllum inophyllum on the basis of spectroscopic analyses and chemical methods. The structure of apetalolide ( 7 ), previously reported from C. apetalum , was revised by means of 2D‐NMR, and the absolute configuration of the known compound inophyllum D ( 8 ) was established by a modified Mosher 's method.
