Chemical constituents from roots of Potentilla anserine / 中草药

ABSTRACT

Objective: To study the chemical constituents from the roots of Potentilla anserine. Methods: The chemical constituents from the roots of P. anserine were isolated and purified by various chromatographic methods and their structures were elucidated on the basis of detailed spectroscopic analysis. Results: Thirteen compounds were isolated from 75% ethanol extract of P. anserine and identified as 2, 19α-dihydroxy-3-oxours-1, 12-dien-28-oic acid 28-O-β-D-glucopyranosyl ester (1), 3β-acetoxy-19α-hydroxyursa-12-en-28-oic acid (2), 3-epi-2-oxopomolic acid (3), 2-oxopomolic acid (4), pomolic acid (5), euscaphic acid (6), arjunic acid (7), potentillanoside B (8), 2-oxopomolic acid 28-O-β-D-glucopyranoside (9), pomolic acid-28-O-β-D-glucopyranoside (10), kajiichigoside F1 (11), rosamultin (12), and adenine (13). Conclusion: Compound 1 is a new triterpenoid saponin, named as potentillanoside G, compounds 3 and 7 are isolated from the plants of genus Potentilla L. for the first time, and compounds 2 and 13 are isolated from this plant for the first time.
