Abstract
Two taraxastane triterpenoids, i.e. taraxast-20-ene-3beta,30-diol (1) and 20alpha,21alpha-epoxy-taraxastane-3beta,22alpha-diol (2), as well as four known triterpenes taraxast-20(30)ene-3beta,21alpha-diol (3), taraxast-20(30)-ene-3beta-ol (4), taraxast-20-ene-3beta-ol (5) and taraxastane-3beta,20alpha-diol (6) were isolated from the Chinese medicinal plant Saussurea petrovii. Their structures were elucidated by spectroscopic methods. These compounds, especially 1 and 2, exhibit significant antitumor and antibacterial activity.
