| Abstract | Manik, Fretty Imelita Timotia. Multilevel Fractionation of Bioactive Compounds of Ethanol Extract of Henna Leaves (Lawsonia inermis L.) Against Staphylococcus epidermidis, Pseudomonas aeruginosa, and Cutibacterium acne Bacteria. Thesis. Pharmacy Study Program, Undergraduate Program, Faculty of Pharmacy, Deli Husada Health Institute, Deli Tua. (Supervisor: apt. Nina Irmayanti Harahap, S.Si., M.Si). Henna leaves (Lawsonia inermis L.) contain the compound lawsone, which acts as a natural dye and has potential antibacterial properties. This study is aimed to determine the antibacterial activity of the n-hexane, ethyl acetate and residual fractions of henna leaves against Staphylococcus epidermidis, Pseudomonas aeruginosa and Cutibacterium acnes. The research results indicated that all fractions were able to inhibit the growth of the three test bacteria at concentrations of 25%, 50% and 75%, with inhibition zone diameters ranging from 7.65 to 15.43 mm. The ethyl acetate fraction exhibited the highest antibacterial activity against Staphylococcus epidermidis, while also demonstrating the best activity against Pseudomonas aeruginosa and Cutibacterium acnes. The research results indicated that an increase in the fraction concentration was accompanied by an increase in the diameter of the inhibition zone.
