Abstract
To study the chemical constituents of Penthorum chinense Pursh. METHODS Many chromatography means were used in separation and purification, and the structures of all compounds were identified by the means of spectroscopic analysis and physico-chemical properties. RESULTS Fourteen compounds were elucidated as: pinocembrin-7-O-β-D-glucopyranoside(1),kaempferol(2),vanillic acid(3),quercetin-3-O-β-D-xylopyranosyl-(1→2)-β-D-galactopyranoside(4), kaempferol-3-O-α-L-rhamnopyranoside(5),pinocembrin(6),quercetin(7),afzelin(8),11-O-galloylbergenin(9),bergenin(10),4-galloylbergenin(11),protocatechuic acid(12),catechins(13),gallic acid(14). CONCLUSION Compounds 1, 3, 6, 7, 8, 12, 13 and 14 are obtained from the title plant for the first time.
