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