Abstract

Abstract Salvilymitone and salvilymitol, two new triterpenoids isolated from Salvia hierosolymitana, have been shown to be 7β,25-dihydroxy-(20 S,24 R)-epoxydammaran-3-one and (20 S,24 R)-epoxydammaran-3β,7α,25-triol, respectively. The absolute stereochemistry of these triterpenoids has been established by an X-ray diffraction analysis of a 25,26,27-trinor derivative obtained by degradation of both compounds. In addition, four previously known triterpenoids were isolated from the same source.
