Abstract: Phytochemical investigationof the plant Clerodendrum serratum var. amplexifolium Moldenke afford a novel condensation compound of a monoterpene acid with a monosaccharide dervative ,named serratumin A(1),and five known compounds(2-6) which have been isolated from the plant source for the first time. Their structures were chracterized by spectral methods (including 2D NMR technique).

Key words: Clerodendrum serratum var.amplexifolium, Verbenaceae, Condensation compound, Serratumin A

摘要： 从云南西双版纳产的三台花(Clerodendrum serratum var. amplexifolium Moldenke)的地上部分分离到6个化合物, 它们的结构通过波谱解析(包括2D NMR 技术)得到鉴定．其中化合物1是一新奇的单萜烯酸和单糖衍生物的缩合物，命名为serratumin A(1)；化合物2～6为首次从该植物中分离得到。
