摘要：
Guided by TNF-α secretion inhibitory activity assay, four taraxastane-type triterpenoids, including two new ones, 22-oxo-20-taraxasten-3β, 30-diol(1) and 22α-hydroxy-20-taraxasten-30β, 30-triol(2), have been obtained from an active fraction of the petroleum ether-soluble extract of the the medicinal and edible plant Cirsium setosum. Their structures were elucidated by spectroscopic data and CD data analysis. In the TNF-α secretion inhibitory activity assay, compounds 1 and 2 were active with the IC50 of 2.6 and 3.8 μmol·L-1, respectively. In addition, compounds 1 and 2 showed moderately selective cytotoxicity against the human ovarian cancer(A2780) and colon cancer(HCT-8) cell lines.
