Studies on chemical constituents from the whole plant of Potentilla multicaulis Bunge

Objective: To study the chemical constituents of Potentilla multicaulis Bunge.. Methods: The constituents of the 70% ethanol extract of the whole plant of Potentilla multicaulis Bunge.were isolated and purified by various chromatographic methods. The structures were confirmed on the basis of physico-chemical properties and spectroscopic data. Results: Four compounds were isolated and identified as vomifoliol(1), ursolic acid(2), tormentic acid(3), oleanolic acid(4). Conclusion: Compouds 1-4 have been isolated from this plant for the first time.
