Objective To study the chemical components of the aerial parts of Echinops gmelini Turcz. Method Chemical constituents were isolated and purified by solvent extraction and chromatographic methods, and their structures were elucidated on the basis of 1H, 13 C NMR and MS spectral data. Results Six compounds were identified: taraxasteryl acetate(Ⅰ), pseudotaraxasteryl acetate(Ⅱ), taraxasterol(Ⅲ), pseudotaraxasterol(Ⅳ), β amyrin acetate(Ⅴ) and β amyrin palmitate(Ⅵ). Conclusion All compounds mentioned above were isolated from genus Echinops for the first time.
