Physicochemical and phytochemical exploration on flower of Delonex regia

Abstract

Delonex regia flower extracts and its different solvent fractionates were evaluated for physicochemical and preliminary phytochemical screening through standard tests. The present study deals with phytochemical explorations of Delonex regia flower including determination of loss on drying, ash values and extractive values. The qualitative chemical examinations revealed the presence of various phytochemicals like flavanoid, terpenoid saponins, phenolic compounds, carbohydrates, tannins and glycosides in the flower extracts of this plant. The presence of various bioactive constituents confirms the application of D. regia for various ailments by traditional practitioners. The study revealed specific identities for the particular crude drug which will be useful in identification and control to adulterations of the raw drug.
