Abstract The ethyl ester of kaempferol 3-O-β- D -glucuronide, the methyl and ethyl esters of quercetin 3-O-β- D -glucuronide have been isolated from an aqueous acetone extract of the flowers of Tamarix nilotica. In addition kaempferol 3-O-sulphate-7,4′-dimethyl ether and the free aglycones were isolated. The structures were established by routine methods, by FAB-MS and by 13C NMR spectral measurements
