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.
心状长圆形红厚壳的嫩枝已被证明含有一种新的吡喃香豆素，即心叶内酯B的甲基醚、三种已报道的吡喃香豆素、心状长圆形酸、木栓酮、异蒲勒醇和蒲公英赛醇。该物种的芽含有大量的吡喃香豆素和少量的甾醇。这一观察结果表明，香豆素合成组织主要位于心状长圆形红厚壳的非木质幼嫩植物部分。
