ABSTRACT: Peucenin 7-methyl ether 1, O-methylalloptaeroxylin 2 and perforatic acid 3 were isolated from the branches of Harrisonia perforata (Blanco.) Merr. (Simaroubaceae). The structures of 1-3 were assigned on the basis of their spectroscopic data and also by a chemical conversion in the case of 3.
