Present study reveals the evaluation of phytochemical analysis and antibacterial activity in different solvents like Aqueous, Ethanol and Chloroform leaf of Phyllodium pulchellum (L.) Desv. The antibacterial screening was carried out by disc diffusion method using six strains of the test micro-organisms including Bacillus subtilis (MTCC 441), Staphylococcus aureus (MTCC 3160), Streptococcus pyogenes (MTCC 442), Pseudomonas aeruginosa (MTCC 424), Klebsiella pneumonia (MTCC 3384) and Escherichia coli (MTCC 443). The crude plant extracts showed broad spectrum activity against all bacteria. The highest inhibitory (IZ 3.4?0.52 cm) was observed in ethanolic leaf extract against Staphylococcus aureus. The results showed that the ethanol leaf extract was more potent than the chloroform extract and aqueous extract. Preliminary phytochemical screening of the leaf extract was carried out and it revealed the presence of alkaloids, flavonoids, steriods, terpinoids, tannins, saponins and phenol. Based on the result it could be inferred that P. pulchellum would be a reliable source for the treatment of some common diseases caused by resistant pathogens.
