Abstract

Alocasia plant (Alocasia macrorrhiza (L.) G. Don) is used as a traditional medicine among diarrhea and antibacterial. This study was aimed to determine the antibacterial activity of the fraction of n-hexane, ethyl acetate and water from sente leaves ethanolic extract against Shigella dysenteria ATCC 9361. Alocasia leaves powder was macerated by ethanol 70%, and then it was fractionated by n-hexane, ethyl acetate, and water. Antibacterial activity test was performed using diffusion for extract and fraction and dilution method test for the most active fraction. The diffusion test used the concentration of 40%, 20% and 10% aimed to determine the most active fraction. The most active fraction was continued dilution test to determine the MBC with concentration of 40%; 20%; 10%; 5%; 2,5%; 1,25%; 0,625%; 0,3125%; 0,156%; 0,078%. Statistical analysis using oneway ANOVA to determine whether there is a significant difference between the test preparation. The results showed that was the fractions and extracts had antibacterial activity against Shigella dysenteriae. Ethyl acetat fraction was most active fraction with dilution test results ethyl acetate fraction showed antibacterial activity with MBC 10%. Keywords: Alocasia leaves, fraction of n-hexane, ethyl acetate fraction, fraction of water, Shigella dyseteriae.
