Article abstract of DOI:10.1016/S0031-9422(00)80549-X

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. - Key Word Index: Tamarix nilotica; Tamaricaceae; flowers; kaempferol 3-O-β-D-glucuronide 6''-ethyl ester; quercetin 3-O-β-D-glucuronide 6''-methyl ester; quercetin 3-O-β-D-glucuronide 6''-ethyl ester; kaempferol 3-O-sulphate-7,4'-dimethyl ether.
