Abstract:
Three new neoclerodane diterpenoids, divinatorins A-C (7-9), have been isolated from the leaves of Salvia divinorum. The compounds were identified by spectroscopic methods as derivatives of the antibiotic (-)-hardwickiic acid (10), which was also isolated, along with four other known terpenoids. Neither the crude extract nor 7-9 displayed antimicrobial activity.
