| Abstract: | To study the chemical constituents in the roots of Crepis tectorum Linn.The constituents were isolated and purified by column silica,HPLC etc,and the structures were identified by physicochemical data,NMR.Three compounds were obtained in the Petroleum ether fractions as ceryl alcohol l(Ⅰ),β-sitosterol(Ⅱ),acetate taraxasterol(Ⅲ);Two compounds were obtained in the Ethyl acetate ether fractions as Caffeic acid(Ⅳ) and ω-taraxasteryl acetate(Ⅴ). |
