Phytochemicals screening test is important for the isolation of new and novel compounds. The current results are directed to the detection of diffident classes of phytoconstituents responsible for the antioxidant properties of Phagnalon niveum. The crude methanolic extract of Phagnalon niveum showed the presence of Alkaloids, Terpenoids, Saponins, Tannins, Steroids and Glycosides, Carbohydrates, monosaccharides, combined reducing sugars and soluble starch. The extracts of P. niveum were screened for secondary metabolites by using methanol, crude extract. The methanolic extracts gave positive results for Alkaloids, Tannins, Flavonoids, Saponins, steroids, Reducing sugar, Terpenoid, Anthraquinone, Phlobatannin and Glycoside. This paper highlights the significance of the plant in traditional medicine and the presence of various phytochemicals in the plant. This study will serve as a benchmark for further detailed analysis of plant extract before drug development and its utilization in future.
