The ' ' C chemical shifts of triterpenoidal olefins and epoxides related to lanosterol are described and discussed. The epoxide function located in the central part of the tetracyclic steroidal skeleton allows the evaluation of epoxidation-induced shifts (EIS) for several carbons. The most character

## Abstract The mass spectra of [17‐^13^C]phyllocladene and [3‐^13^C]methylenecholestane have been examined. It is shown that there are some rearrangements at 70 e V as in the case of [17‐^13^C]kaurene. However, no extensive randomization is evident at the molecular ion level. The results are inter
