New Ursane Type Triterpenes From Salvia Mellifera Greene

Two new triterpenes have been obtained from the aerial part of Salvia mellifera and their structures identified on the basis of spectroscopic data and chemical correlations as 11α-hydroxy-urs-12-en-3-one and 11β-hydroxy-3-oxo-urs-12-en-28-oic acid. the known triterpenes ursolic acid, oleanolic acid, ursa-9(11),12-dien-3-one, ursa-9(11),12-dien-3β-ol, β-amirine and the sterol β-sitosterol were also isolated from the same source.
