Abstract

Six new oleanane-type triterpenes (1- 6), along with five known compounds, were isolated from the flowers and roots of Saussurea muliensis. On the basis of spectroscopic methods, with special emphasis on 1D and 2D NMR techniques, the structures of the new compounds were characterized as 3beta,22alpha-dihydroxyolean-12-en-30-oic acid (1), 3alpha-(E)-caffeoyloxyolean-12-en-30-oic acid (2), 3alpha-(E)-coumaroyloxyolean-12-en-30-oic acid (3), 3alpha,22alpha-diacetoxy-20beta,21alpha,29-trihydroxy-30-norolean-12-ene (4), 3alpha,22alpha-diacetoxy-21alpha,29-dihydroxy-20beta-methoxy-30-norolean-12-ene (5), and 3alpha,22alpha-diacetoxy-20beta,21alpha-dihydroxy-29-palmityloxy-30-norolean-12-ene (6). The isolated compounds (1- 6) were not active against Staphylococcus aureus, Escherichia coli, Bacillus cereus, and Candida albicans.
