Abstract

Objective To investigate the chemical constituents of Rannunculus chinensis Bunge..Methods The chemical constituents of R.chinensis were isolated by chromatography on silica gel and Sephadex LH-20.The structures of compounds were identified by phytochemical properties and spectral analysis(MS and NMR).Results Ten compounds were isolated and identified as quercetin(1),kaempferol(2),luteolin(3),quercitrin(4),protocatechuic acid(5),gallic acid(6),ellagic acid(7),kaempferol-3-O-β-rutinoside (8),β-sitosterol (9) and 7-ketologanin (10).Conclusion Compound 10 is isolated from R.chinensis for the first time.Compounds 1,2,3,4,5,6,7 and 8 are obtained from the title plant for the first time.
