Abstract:
Objective To study the chemical constituents in Crepis turczaniowii C. A. Mey. Method The constituents were isolated and purified by column silica,polystyrene resin RA and polyamide columbine chromatography,and the structures were identified by physicochemical data,MS and NMR. Result Two compounds were obtained in the Petroleum ether fractions as ?-taraxasteryl acetate (Ⅰ) and ?-sitosterol (Ⅱ),and one compound was obtained in the n-BuOH fractions as phillyrin (Ⅲ). Conclusion All above compounds are obtained from the plants of Crepis turczaniowii C. A. Mey. for the first time. Ⅲ is isolated from Crepis L. for the first time.
