Objective To study the chemical constituents of Anemone cathayensis. Methods Some chromatographic methods were used to isolate the chemical constituents from this plant. Their structures were elucidated on the basis of spectral data. Results Eleven compounds were identified as β-sitosterol (1), 4, 7-dimethoxy-5-methyl coumarin (2), 3β-methoxyolean-olean-11-dione-18- (3), α-amyrin (4), 28-hydroxy-olean-12-ene-3, 11-dione (5), ursolic acid (6), 28-hydroxy-α-amyrin (7), cyclocaric acid B (8), 2α, 23- dihydroxyursolic acid (9), β-daucosterol (10), and ereetin-3-7-O-rhanmoside (11). Conclusion All the eleven compounds are isolated from the title plant for the first time.
