The present study deals with the preliminary physico-chemical, qualitative and quantitative phytochemical investigation of three samples of Woodfordia fruticosa flowers from different geographical areas. The dried flowers were extracted successively with various solvents with increasing polarity and all the extracts were subjected to phytochemical screening for the identification of phytoconstituents. The results of qualitative examination revealed the presence of carbohydrates, proteins and amino acids, glycosides, alkaloids, polyphenols, saponins, phytosterols, fixed oils, gums and mucilage, flavonoids and resins. The quantitative analyses further substantiated the findings that alkaloids, saponins and polyphenols are present in the drug. Of significance was the total polyphenol content. The results obtained can be used for the genuine identification of the plant from its adulterants and subsequent screening for potent bioactivity.
