Objective: Investigate the triperpenoids of Saussurea deltoidea with antitumor activities. Method: Use various chromatography methods such as silica gel

RP-18 silica gel

Sephadex LH-20 column chromatography

HPLC

et al. Result: Seven compounds were isolated from the title plant. Their structures were elucidated by spectral analysis. 7 triperpenoids were isolated and elucidated as taraxast-20-ene-3β

30-diol (1)

3β-hydroxy -11-oxo-ursan-12-ene (2)

3β-hydroxy-taraxast-20-ene-30-aldehyde (3)

21α-hydroxy-taraxasterol (4)

ursan-9 (11)

12-diene-3β-ol (5)

ursan-9 (11)

12-diene-3β-O-acetate (6)

3β-hydroxy-9 (11)

12-diene-oleanol (7). Conclusion: All the compounds were isolated from S.deltoidea for the first time.
