A phytochemical investigation of the aqueous ethanolic flower extract of Tamarix tetragyna led to the isolation and characterization of the hitherto unknown conjugates, kaempheride 3,7-dipotassium sulphate and kaempferol 3,4`-dipotassium sulphate as well. Twelve known flavonol compounds, including kaempheride 3-potassium sulphate and kaempheride 3-O-β-glucuronide were also isolated and identified. ¹H- and <sup>13</sup>C-NMR spectra for the known kaempheride derivatives have been recorded and assigned for the first time. Structures of all compounds were established by conventional methods of analysis and confirmed by ¹H-, <sup>13</sup>C-NMR and mass spectral analysis.
