초록

본 연구에서는 식중독 유발세균에 대한 항균활성이 우수한 천연 항균성 물질을 검색하기 위해 예로부터 민간과 한방에서 널리 이용되어 온 백화사설초를 각종 유기용매로 추출하여 식중독 유발세균에 대한 항균활성을 조사해 보았다. 백화사설초를 petroleum ether, chloroform, ethly acetate, methanol를 이용하여 실온에서 각각 용매 별로 계통 분획하고, 열수추출물을 얻은 후, 9종의 식중독 유발세균(Staphylococcus aureus, nacillus cereus, Salmonella enteritidis, Shigella nexneri, Escherichia coli, Salmonella Typhimurium, Shigella dysenteriae, Pseudomonas aeruginosa, Shigella sonnei)에 대하여 항균효과를 조사하였다 백화사설초 추출물의 농도별 항균 활성 검색에서는 백화사설초의 methanol추출물이 가장 큰 항균 효과를 보였으며 S. aureus와 S. flexneri가 가장 민감하게 반응하는 균주였다. 백화사설초의 methanol추출물과 산두근의 ethyl acetate추출물을 혼합하여 항균력을 측정해 본 결과 두 추출물을 섞어 첨가했을 경우가 단독으로 사용했을 시보다 상승효과를 나타내었다. 또한 백화사설초의 methanol추출물이 식중독 유발세균의 성장에 미치는 효과를 검정하기 위해 S. aureus 및 S. Typhimurium의 배양액에 백화사설초의 methanol 추출물을 각각 4,000 ppm농도로 첨가했을 시, S. aureus의 생육이 36시간 이상까지 억제됨을 관찰할 수 있었고, S. Typhimurium의 생육도 24시간까지 지연시킬 수 있었다. 이상의 결과 백화사설초의 methanol추출물은 S. aureus와 S. Typhimurium의 성장을 효과적으로 억제시킴을 알 수 있었다.

This study was performed to investigate the antimicrobial effect of the Hedyotis diffusa extracts against food-borne pathogens. First, the Hedyotis diffusa was extracted with methanol at room temperature and the fractionation of the methanol extracts was carried out by using petroleum ether, chloroform, and ethyl acetate, and methanol respectively. The antimicrobial activity of the Hedyotis diffusa extracts was determined by using a paper disc method against food-borne pathogens and food spoilage bacteria. The methanol extracts of Hedyotis diffusa showed the highest antimicrobial activity against Staphylococcus aureus and Shigella flexneri. Synergistic effect in inhibition was observed when Hedyotis diffusa extract was mixed Sophora subprostrata extract as compared to each extracts alone. Finally, the growth inhibition curves were determined by using ethyl acetate extracts of Hedyotis diffusa against Staphylococcus aureus and Salmonella Typhimurium. The methanol extract of Hedyotis diffusa had strong antimicrobial activity against Staphylococcus aureus at the concentration of 4,000 ppm. At this concentration, the growth of Staphylococcus aureus was retarded more than 36 hours and up to 24 hours for Salmonella Typhimurium. In conclusion, the methanol extracts of Hedyotis diffusa inhibit efficiently Staphylococcus aureus and Salmonella Typhimurium.
