Abstract

Ipomoea pes-caprae (L) R. Br leaves have chemical contents of saponin, flavonoid and tannin are thought to have antibacterial activity. The purpose of this study was to determine the activity of ethanolic extract, n-hexane, ethyl acetate and water fractions from Ipomoea pes-caprae (L) R. Br leaves as antibacterial of Staphylococcus aureus ATCC 25923. Ipomoea pes-caprae (L) R. Br leaves was extracted by maceration using 70% ethanol then fractionated using n-hexane, ethyl acetate and water solvents. Ethanolic extract, n-hexane, ethyl acetate and water fractions were tested the antibacterial activity using dilution method, with concentration of 50%, 25%, 12.5%, 6.25%, 3.13%, 1.57%, 0.79%, 0.40%. The result obtained that ethyl acetate fraction of Ipomoea pes-caprae (L) R. Br leaves had the most active antibacterial activity than others. Ethanolic extract was bactericidal at concentrations of 12,5%, while ethyl acetate fraction at concentration of 6,25% and water fraction were not bactericidal against Staphylococcus aureus ATCC 25923.
