The pentacyclic triterpene composition of a southern California variety of Salvia apiana (fam. Labiatae) has been assessed. The presence of α-amyrin, oleanolic acid and ursolic acid has been established. Separation of α-amyrin from a closely related impurity believed to be β-amyrin was accomplished by subjecting the mixture to selenium dioxide oxidation and isolating α-amyrin by preparative thin-layer chromatography on silver nitrate-silica gel. Evidence for the presence of isomeric mixtures of two dihydroxy triterpenes and two triterpene aldehydes representing intermediate stages of oxidation from α- and β-amyrin to ursolic and oleanolic acids was presented. Isolation of ursolic acid from a Mexican variety of Salvia karwinskii was also reported.
