초록

선복화(Inula britannica flowers) 메탄올 추출물을 이용하여 methicillin에 저항성이 있는 Staphylococcus aureus (MRSA)에 대한 항균효과를 검증하였다. 선복화 메탄올 추출물은 다량의 quercetin을 함유한 것으로 분석되었다. 세 종류의 MRSA에 대한 항균효과는 disc diffusion method에 의해 확인되었고, 최소저해농도(MIC) 및 최소사멸농도(MBC)는 각각 0.625 mg/ml-1.25 mg/ml, 2.5 mg/ml로 확인되었다. 이들 MRSA 중 S. aureus ATCC 33591가 가장 민감한 작용을 하였으며, 이 균에 대해서 작용기작을 확인하였다. 시간에 따른 저해 정도와 형태관찰을 통해 선복화 메탄올 추출물이 항균활성을 갖는 것을 확인할 수 있었다. 메탄올 추출물의 resistant gene에 대한 영향은 mRNA 상에서 mecA와 mecRI gene의 발현감소와 mecI gene의 발현증가를 통해 메티실린 내성을 감소시키는 것을 알 수 있었다. 따라서 선복화 메탄올추출물은 MRSA에 대한 항균효과를 가지는 천연 항균성 소재로서의 가능성을 확인할 수 있었다.

The antimicrobial effect of the methanol extract of Inula britannica flowers against methicillin resistant Staphylococcus aureus (MRSA) was investigated. It was confirmed that the methanol extract is mainly composed of quercetin, which has antimicrobial properties. The antimicrobial effect of the methanol extract against 3 MRSA strains was determined by the disc diffusion method. The minimal inhibitory concentrations were ranged from 0.625 mg/ml to 1.25 mg/ml, and the minimum bactericidal concentrations were 2.5 mg/ml. Time kill kinetics revealed bactericidal activities, and the morphological alterations in S. aureus ATCC 33591 treated with the extract were observed using a scanning electron microscope. The methanol extract affected the expression of the resistant genes, mecA, mecI, and mecRI in mRNA. Therefore, the methanol extract of I. britannica flowers clearly demonstrated an antimicrobial effect against MRSA and these results suggest a potential for application as a natural antimicrobial agent.
