Abstract: The present investigation deals with the preliminary phytochemical estimation of bio-functional partsi.e.Leaves and Tubers. Aquatic starchy tuberous plant Sagittariasagittifolia L. belonging to family Alismataceae, commonly known as Arrowhead. The biofunctional parts were extracted with five different organic solvents viz. Ethanol, Methanol, Acetone, Petroleum Ether, Chloroform and Distilled Water for their primary and secondary phytochemicals and their active constituents like Tannin, Saponins, Flavonoids, Phenols, Steroids, Glycosides, Protein, Amino-acids, Starch, Reducing sugars and Alkaloids. The results show the 31.1±0.08 extract of leaf and 35.7±0.15extract of tuber shows higher extractive value. The presence ofmaximum phytochemicals viz. glycosides, steroids, tannins, saponins, terpenoids, flavonoids, carbohydrates, alkaloids, and phenols in ethanol while minimum presence in acetone followed by aqueous.Thesephytochemicalsare useful in medicinal and therapeutic system as well as in traditional and modern medicinal system.
