Abstract

Ashitaba (Angelica keiskei [Miq.] koidz) leaf contains alkaloid, saponin, tannin, flavonoid and terpenoid. The study was conducted to determine the antibacterial activity ethanol extract, fractions of n-hexane, ethyl acetate, and water from ashitaba (Angelica keiskei [Miq.] koidz) leaf against Salmonella typhi ATCC 19430. Ashitaba leaf extraction using maceration method with solvent of 96% ethanol, and then fractionated using n-hexane, ethyl acetate, and water. The results of extraction and fractionation was tested antibacterial activity against Salmonella typhi ATCC 19430 using dilution method. The concentration of ethanol extract and fractions used were 40%; 20%; 10%; 5%; 2,5%; 1,25%; 0,625%; 0,313%; 0,156%; 0,078%. The results of this study showed that the ethanol extract, fractions of n-hexane, ethyl acetate and water had antibacterial activity against Salmonella typhi ATCC 19430 with Minimum Kill Concentration 20%, 40%, 10% and 40%, respectively. Ethyl acetate fraction of ashitaba leaf had the most active antibacterial activity than the fractions of n-hexane, water and extract. Keywords: Angelica keiskei [Miq.] koidz.,Salmonella typhi ATCC 19430, antibacterial.
