Abstract: The genus Crotalaria belongs to the family Fabaceae which is the third largest genus of this family, containing approximately six hundred species widely distributed in tropical and subtropical regions of the world. The annual erect herb Crotalaria pallida Aiton is referred to as “rattlesnake,” C. pallida is frequently used in traditional medicine to treat a wide range of ailments, including diarrhoea, diabetes, skin infections, snake bites, and urinary issues. An experimental study was undertaken to assess the phytochemical constituents of C. pallida by using methanol as solvent for the extraction of aerial parts of the plant. The sieved plant powder was soaked in methanol at 1:5 ratio in glass containers for one week and then filtered and subjected to extraction using rotary evaporator (hot extraction method). Finally obtained gummy extract was used for phytochemical screening tests. The distilled water was used as solvent for extract for some of the tests. All the tests were performed as per standard protocol using the chemicals and reagents procured from authenticated chemical manufacturers and results were recorded. The Physical characteristics, per cent yield were also estimated in which per cent yield was 3.702%, dark brownish green colour and gummy-sticky consistency of extract were also found. The phytochemical screening of C. pallidarevealed the presence of alkaloids, flavonoids, phenolic compounds, tannins, phytosterols and triterpenoids, while the extract was negative for the presence of carbohydrate, amino acids and protein. The phytoconstituents of the plant might play an important role in therapeutic and toxic properties.
