Abstract
From the ethanolic extract of the total herb of Pulicaria undulate (L.) Kostel; five flavonoids were isolated. Their structures were established by physical, chemical and spectral, methods (UV, IR, NMR and MS) and proved to be: 7-methoxy kaempferel (Rhamnocitrin), 3,7 dimethoxy quercetion, 7-methoxy quercetin (Rhamnetin), dihydrokaempferol and quercetin 3-o-glucoside (Isoquercetrin).
A chromatospectrophotometric method was adopted for quantitative estimation of these flavonoids.
