PRIMARY STUDIES ON ANTIMICROBIAL ACTIVITY OF HONDURAN MAHOGANY (Swietenia macrophylla) LEAF EXTRACT

The present study was designed to evaluate the antibacterial activities of Swietenia macrophylla crude methanolic (SMCM) seed extract. The antimicrobial activity of the oily extract against Gram-positive, Gram-negative, yeast and fungus strains was evaluated based on the inhibition zone using disc diffusion assay, minimal inhibition concentration (MIC) and minimal bactericidal concentration (MBC) values. The crude extract was subjected to various phytochemicals analysis. The demonstrated qualitative phytochemical tests exhibited the presences of common phytocompounds including alkaloids, terpenoids, antraquinones, cardiac glycosides, saponins, and volatile oils as major active constituents. The SMCM seed extract had inhibitory effects on the growth of Candida albicans, Bacillus subtilis, Escherichia coli, Pseudomonas aeruginosa and illustrated MIC and MBC values ranging from 25 mg/ml to 50 mg/ml.
