Preliminary Study of Antimicrobial Activities on Mangosteen
To investigate medicinal properties form Thai fruit as natural antimicrobial agents, Mangosteens were selected to screen for antimicobial activities. Fresh extracts and oil extracts of Mangosteen in this study were tested against food poisoning bacteril: Bacillus cereus, Salmonella typhiand Staphylococcus aureusby using Agar Diffusion Method. Screening for antimicrobial activities of Mangosteens was performed in duplication. Oil extract from the outer peel, the inner peel and flesh of mangosteen showed antimicrobial activities against Bacillus cereus and Staphylococcus aureus. Only Salmonella typhishowed no anti microbial activity. In addition, it was found that mangosteen fresh extract showed no antimicrobial activities, but oil extract showed high activity. The negative control test, 95% ethanol without peel, showed no inhibitory effect on microbial activity. Potential of outer peel, inner peel, and flesh of mangosteen as antimicrobial agent have been concluded. The process development on Mangosteen waste utilization as natural drug has been suggested.
