Abstract

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.
