Flavonoids in Leguminosae: Analysis of extracts of T. pratense L ., T. dubium L ., T. repens L., and L. corniculatus L . leaves using liquid chromatography with UV, mass spectrometric and fluorescence detection

Abstract  Reversed-phase LC on C-18 bonded silica with a methanol–ammonium formate gradient was used to determine the main flavonoids in leaves of four species of the Leguminosae family. The detection modes were diode-array UV absorbance,
