Seven new neo-clerodane diterpenes, salvidivins A (2), B, (3), C (4), and D (5), salvinorins H (6) and I (7), and divinatorin [corrected] F (8), along with eight known neo-clerodane diterpenes, salvinorins A (1)-F, divinatorins A and B, and seven other constituents, were isolated from the hallucinogenic sage Salvia divinorum. The structures of 1-7 were elucidated on the basis of 2D NMR spectroscopic studies.
The simple and efficient method for the preparative isolation of lancemaside A along with two other saponins, foetidissimoside A and astersaponin Hb, from the saponin fraction of C. lanceolata was established using CPC.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
