摘　　要：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,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 resolution 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.
