title: 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.
