从小盘木植物中分离鉴定了四个新二萜类化合物1~4,分别属于dolabrane烷型、玫瑰烷型、半日花烷型以及烟草烷型.综合利用各种光谱数据阐明了四个二萜类化合物的相对立体结构,并通过圆二色谱(ECD)数据确定了它们的绝对构型.

Four new diterpenoids, casearoids A~D (1~4), including dolabrane, orosane, labdane, and cembrane, were isolated and characterized from Microdesmis casearifolia. Their structures were elucidated by extensive spectroscopic data analysis. The absolute configurations of these diterpenoids were established by analysis of the electronic circular dichroism (ECD) data.
