บทคัดย่อ (EN): This study aimed to extract essential oils from some local Thai medicinal plants, namely Citrus hystrix DC. (Kaffir lime), Cymbopogon citratus Stapf. (Lemon grass), Cymbopogon nardus Rendle (Citronella grass) and Ocimum basilicum L. (Sweet basil) by hydro-distillation method and investigate their antimicrobial efficiency against four common bacteria species. By hydro-distillation method, the highest percentage yield was found from the essential oil extracted from sweet basil (1.19%), whereas lemon grass gave the lowest percentage yield of the essential oil (0.28%). Agar-disc diffusion technique was used to test for the antimicrobial activity of these essential oils against Staphylococcus aureus, Escherichia coli, and Salmonella Group B, isolated from specimens of patients from Kalasin Hospital. The result showed differences in antimicrobial efficiency of each essential oil against the same human pathogen. Essential oil, extracted from lemon grass, showed higher tendency to inhibit all pathogens. Antimicrobial index (AI) was used to report the antimicrobial efficiency. Result showed that S. aureus and Salmonella Group B were the most sensitive to the essential oil extracted from lemon grass, showing their AI as 5.07 and 1.15, respectively. The highest AI against E. coli was found when testing with the essential oil from citronella grass, followed by lemon grass, their AI as 2.28 and 2.22, respectively. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of essential oil extracted from lemon grass against the indicator strains were in the range 62.5-500 ppm. This result suggested the promising antimicrobial property of the essential oil from lemon grass could be useful in pharmaceutical treatment.
