Abstract: Twigs of Calophyllum cordato-oblongum have been shown to contain a new pyranocoumarin, the methyl ether of cordatolide B, three reported pyranocoumarins, cordato-oblongic acid, friedelin, canophyllol and taraxerol. Buds of this species contained large quantities of pyranocoumarins and a small amount of sitosterol. This observation indicates that the coumarin-synthesising tissues are mainly located at the non woody young plant parts of C. cordato-oblongum.
