Steroids from Saussurea ussuriensis.
One novel and seven known steroids were isolated from the alcohol extract of the whole plant of Saussurea ussuriensis. The structure of the new compound was elucidated as stigmast-5-en-3beta,7alpha,22-triol (1) by spectroscopic methods including intensive 2D NMR techniques (H1-H1 COSY, gHSQC, gHMBC) and HR-SI-MS and the known compounds were identified on the basis of comparing their NMR data with those of corresponding compounds in the literature.
