| Abstract: | Objective To study the chemical constituents of the 70% ethanol extract of the aerial parts of Polygonum capitatum Buch-Ham ex D. Don. Methods The constituents were isolated by several chromatography methods and identified by physico-chemical characters and spectroscopic analysis. Results Eleven compounds were isolated and identified as: quercetin (1) , kaempferol (2), quercitrin (3) , protocatechuic acid (4), gallic acid (5) , protocatechuic acid ethyl ester (6) ,ethyl gallate (7), vanillic acid (8) , 1,5,7-trihydroxyl-3-methylanthraquinone (9), succinic acid (10) , 5-hydroxymethylfuraldehyde (11).Conclusion Compounds 6,7,9,11 are isolated from this genus for the first time. |
