从产自豆科植物云实（Caesalpinia bonduc）种子的菲律宾生药calumbibit中分离得到两个新的二萜类化合物，分别命名为新云实碱C和D，并通过波谱学方法鉴定了它们的结构。这些化合物的特征在于存在a，b-丁烯二酸部分。虽然一些卡桑呋喃二萜已被称为发生在同一种植物，这些成分不能从菲律宾原产的生药在这项研究中分离出来。推测这种化学差异是由物种的化学分化引起的。
New cassane diterpenes named neocaesalpins C and D were isolated from the Philippine crude drug calumbibit botanically originating from the seeds of Caesalpinia bonduc (Fabaceae), and their structures were elucidated on the basis of the spectroscopic evidence. These compounds are characterized by the presence of the a,b-butenolide moiety. Although a number of cassane furanoditerpenes have been known to occur in the same plant species, such constituents could not be isolated from the crude drug of Philippine origin in this study. It is presumed that the chemical difference resulted from chemical differentiation of the species.
