Methods: Study included phytochemical screening and in vitro antibacterial testing of ethanol extract, n-hexane fraction and ethyl acetate of Sungkai leaves against Salmonella typhi. Results: obtained groups of chemical compounds alkaloids, flavonoids, glycosides, anthraquinones, tannins and triterpenoids/steroids on Sungkai leaf powder. Ethanol extract of Sungkai leaves obtained resistance at a concentration of 20% by 12.7 mm, and inhibition of the ethyl acetate fraction at a concentration of 20% of 14.8 mm. Conclusion: Ethyl acetate fraction of Sungkai leaves have antibacterial properties against S. typhi which is greater than ethanol extract and hexane fraction of leaf heal.
