Objective: To study the chemical constituents of Potentilla multifida L. Methods: Chemical constituents were isolated by the repeated silica gel chromatography and Sephadex LH 20, and their structures were identified by the spectral analysis. Results: Five compounds were obtained as follows: 3β,24 dihydroxyl urs 12 ene (1), ursolic acid (2), euscaphic acid (3), tormentic acid (4), and epihedaragenin (5). Conclusion: Five compounds were isolated from this plant for the first time. Compounds 1 and 5 were isolated from this genus for the first time. Compound 1 was a new natural product.
