Abstract

One of the causes of diarrhea is the E. coli bacteria. The leaf‘s Mango kasturi used to treat diarrhea (parves 2016). Mango kasturi leaf contain flavonoid, saponin, tanin and triterpenoid. This research is being done in purpose to find out the antibacterial activity of n-hexane, ethyl acetate and water fractions from the mango casturi leafs to E. coli ATCC 25922 bacteria. The powder of mango casturi was extracted with maceration method using methanol solvent. The test for the antibacterial activity in this study uses two methods: disc diffusion and dilution.The test of the antibacterial activity by disc diffusion method using 25% concentration of extract, n-hexane, ethyl acetate and water fractions from mango kasturi leaf’s. The test of the antibacterial activity by dilution method using the most active fraction obtained from the diffusion method. Based on research that has been done extract, of n-hexane, ethyl acetate and water fractions have antibacterial activity. The extract, n-hexane, ethyl acetate and water fractions having inhibitory diameter with 25% concentration had of 10.5 mm, 8.2 mm, 21.2 mm, 8.9 mm and the result of antibacterial activity test ethyl acetat fraction by using dilution method obtained by CMB 3,125%.
