Abstract

The aim of the present study is to investigate the antimicrobial potency of leaves from various extracts of Capparis zeylanica, Streblus asper and Tribulus terrestris were evaluated. In addition, this is the first report on MIC, MBC/MFC antimicrobial activities of above mentioned plants and also identify the phytochemical, functional groups by GC-MS and FT-IR respectively. Soxhlet extraction method was used for preparation of different extracts viz., aqueous, petroleum ether, ethyl acetate and methanol. The extracts were examined against Staphylococcus epidermidis, Enterococcus faecallis, Salmonella paratyphi, Shigella dysenteriae, Candida albicans and Mycobacterium tuberculosis by agar well diffusion method, and Minimum Inhibitory Concentratioon (MIC), Minimum Bactericidal/Fungicidal Concentration (MBC/MFC) values were determined through micro dilution method. Phytochemical analysis of compounds was carried out by GC-MS analysis and functional groups were identified by FT-IR. Based on the outcome of our results, Ethyl acetate extract Showed significant antimicrobial activity against the tested pathogens especially, for C. albicans (40 mm) followed by ethyl acetate of S. asper against S. paratyphi (38 mm). While, the least inhi...Continue Reading
