The internal tissue flavonoids of P. senegalense are glycosides, based mostly on
quercetin. Chromatography on silica gel and Sephadex LH-20 of the hydrophilic extract resulted
in the isolation and characterizationof quercetin-3-1l-0-galactoside(1), quercetin-3-f3-0-glucoside
(2), quen:etin-3-(2" -galloylglucoside) (3) and a new compound 2' -glucosyl-4' -hydroxy-6'-
methoxydihydrochalcone (or uvangolatin-Z' -B-O-glucoside) (4).
