Journal Title: World Journal of Pharmaceutical Research - Year 2019, Vol 8, Issue 8
Abstract
Objective: This study was designed to compare the antibacterial effect of nutmeg seed extracts (Myristica Fragrans Houtt) on the common causative bacteria of skin infection, Staphylococcus aureus and S. epidermidis. Methods: The antibacterial effect of the nutmeg seed extracts was analyzed using the agar diffusion method. The determination of extracts Minimum Inhibitory Concentration (MIC) was done using the macrodilution method. In addition to the antibacterial effect conclusion, the antibacterial effect of the extract was evaluated on both staphylococcus strains using the neomycin sulfate as the standard antibiotic. The comparative method was the agar diffusion method, followed by the inhibitory diameters data plotting to log concentration of the extract or neomycin sulfate, thus an inhibition curve was obtained. Results: The antibacterial activity of nutmeg seed extract on S. aureus was stronger then to S. epidermidis. This data was supported by comparing the MIC value of the extract on both strains. The MIC value of the extract against S. aureus (0.156<x≤3.125%w/v) was lower than to S. epidermidis (0.3125<x≤ 0.625%w/v). In comparison with neomycin sulphate, the comparative activity value of the test extract against neomycin sulfate on S. aureus was 1: 11.119, while on the S. epidermidis was 1: 15.865. Conclusion: The nutmeg seed extract is more potential to be a antibacterial agent for infections caused by S. aureus than S. epidermidis.
