用EIMS、高分辨及B/E联动扫描技术, 对二十一个20-C-未被氧化的-对映-贝壳杉烯化合物的结构特征进行了研究, 根据它们的结构和质谱行为, 分为三种类型的化合物,B环的7C上有取代基, B环的6C上有取代基, B环的6C和7C同时有取代基, 并讨论裂解过程与A、B、C环上的取代基的影响。

The mass spectra of twenty one 20-C-nonoxygenated-ent-kaurenes have been analyzed by the high resoln. EI mass spectrometry and B/E linked-scanning technique. According to the structures and mass spectrometric behaviors of these compounds, they were classified into three groups. The dependence of their pathways of fragmentation on the functionality of A/B/C rings has been discussed and rationalized.
