Abstract

Chili leaves (Capsicum frutescens L.) contains flavonoids, saponins, alkaloids, and tannins that are suspected of having antibacterial activity. The purpose of this research was to know antibacterial activity of ethanol extract 70%, fraction of n-hexane, ethyl acetate, and water from chili pepper leaves (Capsicum frutescens L.) againt Escherichia coli ATCC 25922. Chili leaves powder was remacerated with ethanol 70% then fractionated with n-hexane, ethyl acetate and water. The ethanol extract was 70%, and the fractions were tested for antibacterial activity using diffusion method, with concentration of 50%, 25%, and 12,5% to determine the most active extract or fraction, followed by antibacterial activity test using dilution method, with concentration 50%; 25%; 12.5%; 6.25%; 3.125%; 1.5625%; 0.7813%; 0.3906%; 0.1959%; 0.0977% against the bacterium Escherichia coli ATCC 25922. The diameter of inhibitory power was measured and statistically analysed using ANOVA. The results showed that 70% ethanol extract, of n-hexane fraction, ethyl acetate, and water from chili pepper leaves (Capsicum frutescens L.) had antibacterial activity, and ethyl acetate fraction of chili pepper leaves had the most active antibacterial activity against Escherichia coli ATCC 25922, with a minimum kill concentration of 12,5%. Keywords: Capsicum frutescens L, Escherichia coli ATCC 25922, diffusion, dilution.
