Abstract

Siwak Wood (Salvadora persica L) substances chemical that are antibacterial and antifungal. Siwak Wood Chemical cobstituents are flavonoid, alkaloid, saponin and tanin. The research was conducted to determins the fraction activity n-hexsan, ethyl acetate, Water and etanol extracts of siwak wood (Salvadora persica L) as antibacterial against Staphylococcus aureus ATCC 25923. Fraction most activity hampered Staphylococcus aureus ATCC 25923, KHM and KBM of fraction most activity for Staphylococcus aureus ATCC 25923. The extraction of siwak Wood using percolation method with 70% etanol solven, Then fractionated using the solvent n-hexane, ethyl acetate and water. The results of fractionation of the antibacterial activity tested against Staphylococcus aureus ATCC 25923. Concentration of the extract and fraction used for the diffusion method was 50%, 25%, and 12,5%. Whereas the concentration for the dilution method was 50%, 25%, 12,5%, 6,25%, 3,12%, 1,56%, 0,78% and 0,39%. The results showed the extract, fraction of n-hexane, ethyl acetate fraction and water fraction of ethanol extract of siwak wood has antibacterial activity against Staphylococcus aureus ATCC 25923 and ethyl acetate fraction had the most effective antibacterial activity against Staphylococcus aureus ATCC 25923 with a kill minimum concentration of 3.12%. Keywords: Siwak wood, fractionation, Staphylococcus aureus, antibacterial.
