From the aerial part of Chrozophora obliqua, 14 novel dolabellane dite
rpenoids have been isolated, all of them are naturally acylated at the
C-16 hydroxyl group with 3-hydroxy-3-methylglutaric acid (HMG). The s
tructures of the isolated compounds were assigned on the basis of deac
ylation reactions as well as NMR and FAB-MS spectroscopic studies.
