1School of Pharmacy, Second Military Medical University, Shanghai 200433, China.
Objective:
Investigating the chemical constituents in the root of Rumex patientia.
Method:
Compounds were separated by rechromatography on silica gel. Their structures were determined by spectral analysis and chemical evidence.
Result:
Eight compounds were isolated and identified as 5-methoxy-7-hydroxy-1 (3H)-benzofuranone (I), 5, 7-dihydroxy-1 (3H)-benzofuranone(II), nonadecanoic acid-2,3-dihydroxypropyl ester(III), torachrysone-8-O-beta-D-glucopyranoside(IV), gallic acid(V), beta-sitosterol(VI), beta-sitosterol-3-O-beta-D-glucopyranoside(VII) and catechin(VIII).
Conclusion:
Compound III is a new natural products, and compounds I and II were obtained from this plant for the first time.
