| Abstract: | 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: 3beta,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. |
