[Study on steroids of Cacalia tangutica].
Seven steroids and two cumarins were isolated from the petroleum ether extract of the specie Cacalia tangutica of the family Compositae which were collected in Minhe county, Qinhai province of China. The structures were identified as Stigmast4-en-3beta, 6beta-diol (1), 24-ethyl-5alpha-cholestane-3beta, 5, 6beta-triol (2), 7beta- methoxy-stigmast-5-en-3beta-ol (3), Schleicherastatin 1 (4), Stigmast-5-en-3beta, 7alpha-diol (5), umbelliferone (6) and hydrangetin (7) by the means of chemical and modern spectroscopic analysis (MS, 1H-NMR, 13C-NMR, DEPT). The compounds 1-5 were isolated from Cacalia tangutica for the first time.
