Abstract
Introduction: Medicinal plants contribute to human’s health and well -being. People use medicinal plants as traditional medicine for generations. One of the folk medicine that is easy to find , yet has beneficial effect and low cost is Averrhoa bilimibi . A. bilimbi or ‘ Belimbing Wuluh ’ in Indonesian which are a native Indonesia’s plant, is now cultivated in many countries . It is used as a treatment for cough, fever, mumps, bilious colic, stomach ache, etc. Many studies have proven that A.bilimbi extract has antidiabetic, antimicrobial, antiinflammatory , cytotoxic , antioxidant , and infert ility effect . Nowadays , many bacteria are resistant to antibiotic. Salmonella typhi which causes typhoid fever is resistant to multidrug s: ampicillin, chloramphenicol, cotrimoxazole and less sensitive against quinolones such as ciprofloxacin. To avoid fur ther resistance, traditional medicine is needed. The present study was carried out to determine the in vitro antibacterial activity of ethanol extract of Averrhoa bilimbi leaves against Salmonella typhi. Methods: This study was based on laboratory experimental. The samples wereethanol extract of Averrhoa bilimbi leaves and Salmonella typhi . A. bilimbi leaves were from Balai Materia Medika . The et hanol extraction was performed at Pharmacognosy and Phytochemistry Laboratory Faculty of Pharmacy Universitas Airlangga . S. typhi was from Microbiology Laboratory Faculty of Medicine Airlangga Univers ity . Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) values were determined by dilution method. The concentrations used in determination for MIC were 500mg/ml, 250mg/ml, 125mg/ml, 62. 5mg/ml, 31. 25mg/ml, and 15.625mg/ml. The MBC value were determined by suspension streaking from Mueller -Hinton broth to nutrient agar plate.The result was analyzed by description method. Results :The MIC value could not be determined due to turbidity of the extract and t he MBC value was at 500mg/ml. Conclusion :Ethanol extract of Averrhoa bilimbi leaves have antibacterial activ ity against Salmonella typhi . MIC of ethanol extract of Averrhoa bilimbi leaves against Salmone lla typhi c ould not be determined. MBC of ethanol extract of Averrhoa bilimbi leaves against Salmonella typhi was at 500mg/ ml.
