Lawsonia inermis is frequently known as ‘henna’ in English and ‘inai’ in Malay which is acknowledged in traditional medication scheme. It has been customarily detailed in utilize of migraine, bruises, antibacterial and numerous more. Be that as it may, with all these potential benefits, this plant is not broadly utilized. Using of disinfectant are already being applied long before as antimicrobial agent to inhibit the microorganism. Dettol and Chlorox are the common hospital disinfectants used but the ingredient contains in the disinfectants can be harmful to humans. In order to address these issues, it has become a necessary for the researcher to explore other types of antimicrobial agents from natural product as alternative way in disinfecting. Thus, this study is carried out to assess the efficacy of L. inermis extracts, towards the advantage of mankind as surface disinfectant and compare with Dettol and Chlorox against tested organisms. The L. inermis leaves was extracted with ethanol. The antimicrobial efficacy of L. inermis extracts, Dettol and chlorox were determined using the disc diffusion technique at four distinctive concentrations against four organisms. In this study, Staphylococcus aureus, Staphylococcus epidermidis, Pseudomonas aeruginosa, and Escherichia coli were used as the tested organisms. The result obtained indicated that L. inermis has antimicrobial activity against all the tested organism but significantly difference when compared to Dettol as the p-value < 0.05 but not significantly difference when compared to Chlorox as the p-value > 0.05. Thus, this finding appeared that L. inermis leaves extract had a potential to be replace as natural surface disinfectant within the future.
