Plants have always been an important source of medicines since ancient times and seventy percent of the worldwide population still relies on one or other forms of traditional plant based medicine. Plant items have been essential for phytomedicines since days of yore. These can be derived from any part of the plants like bark, leaves, flowers, roots, fruits, seeds, etc. The present exploration has been conducted in the leaf of Senna tora performing various phytochemical tests to identify the secondary metabolites present in it such as alkaloids, flavonoids, sugars, glycosides, saponins, steroids, tannins, phenolic compounds, Vitamin C, proteins, amino acids and carbohydrates. The maximum phenolic content was presented in methanol solvents 1.41 ± 0.44 and lowest content was presented in petroleum ether extract 0.17 ± 0.21. Antibacterial activity were estimated and evaluated by using different types of extract against Escherichia coli, Klebsiella pneumoniae, Pseudomonas stutzeri, Bacillus thuriengensis and Staphylococcus. Among these the maximum antibacterial activity (Zone of inhibition 19.0 mm) shown against Klebsiella pneumoniae in the extract of Petroleum ether. The minimum antibacterial activity observed (Zone of inhibition 11.0 mm) against Staphylococcus ceureus in extract of Ethanol extract of Senna tora (L.) Roxb.
