The aim of the study is to evaluate the antibacterial activity of Pistacia integerrima, Cedrus deodara and Gymnema sylvestre against seven different microorganisms such as Escherichia coli, Salmonella typhi, Klebsiella pneumoniae, Proteus vulgaris, Pseudomonas, Bacillus subtillis and Staphylococcus aureus by using disc diffusion method. Preliminary studies with ethanol extract and water extract of plants indicated that the growth of test organism was markedly inhibited by ethanol extract of Pistacia integerrima and Gymnema sylvestre. But in case of Cedrus deodara, water extract was more effective. Efficacy of plant extract which showed variable inhibitory activity against each bacteria was compared to standard antibiotic (tetracyclin). The two extracts were subjected to qualitative analysis to find out phytoconstituents present . Results showed that Pistacia integerrima contained all the phytochemicals, so exhibited higher antibacterial activity. |
