Five new natural labdane-type diterpenoids (5-9), designated leoheteronins A-E, together with four known diterpenoids (1-4), two phytosterols as a mixture of beta-sitosterol and stigmasterol, and the flavone genkwanin (10) were isolated from the aerial parts of Leonurus heterophyllus SW. (Lamiaceae) collected in northern Vietnam. Compound 1 was isolated for the first time from a Leonurus species, and 10 is considered to be a chemotaxonomic marker of the Leonurus genus. Their structures were determined using spectroscopic analyses.
从采自越南北部的益母草（唇形科）地上部分分离得到了5个新的天然半日花烷型二萜类化合物（5-9），命名为益母草异壬素A-E，以及4个已知的二萜类化合物（1-4）、两种植物甾醇（β-谷甾醇和豆甾醇的混合物）和黄酮芫花素（10）。化合物1首次从益母草属植物中分离得到，化合物10被认为是益母草属的化学分类学标志物。通过光谱分析确定了它们的结构。
