Tri-Nordammarane Triterpenoids and Neoclerodane Diterpenoids From Salvia Aspera (Labiatae)

Abstract

From the aerial parts of Salvia aspera one new tri-nordammarane named amblyol ( 1 ) was isolated besides amblyone ( 2 ). An X-ray analysis was performed on compound 1 . In addition, three known neoclerodane diterpenoids were also isolated. The structures of these compounds were established by spectral and chemical methods. The presence of dammarane triterpenoids in a Mexican Salvia is described for the first time.
