정향과 황련 혼합물의 항균 및 항염증 활성 연구

Anti-inflammatory and anti-bacterial effects of a mixture of Syzygium aromaticum and Coptis japonica

본 연구는 정향, 황련 추출물을 혼합하여 Malassezia furfur에 대한 항균 능력을 확인하고 최적의 혼합물을 만들어 항산화 및 항염증 능력을 평가하기 위해 수행되었다. 정향과 황련을 70% 에탄올, 100% 메탄올, 열수로 추출하여 항균 능력을 평가하여 정향은 100% 메탄올 추출물, 황련은 열수 추출물이 가장 항균 능력이 높은 것을 확인하였다. 또한 두 추출물을 혼합하여 비율별로 항균 능력을 평가하였을 때 9:1 비율이 가장 우수한 활성을 보였고 혼합물의 항산화 활성이 뛰어남을 확인하였다. Raw 264.7 세포에서 생존율에 영향을 미치지 않는 1, 10, 50, 100 µg/mL에서 LPS를 이용하여 염증 반응을유도하고 항염증 활성을 확인한 결과 10, 50, 100 µg/mL에서 No 생성 저해율과 IL-6 발현 저해율 및COX2, iNOS 단백질 발현 저해 활성이 뛰어남을 확인하였다. 본 연구를 통해 정향 메탄올 추출물 및 황련 열수 추출물의 혼합물은 항균, 항염증 효능이 뛰어나기에 기능성 화장품의 천연 소재로써 사용이가능할 것으로 사료된다.

This study was conducted to check the anti-bacterial ability against Malassezia furfur by mixing Szygium aromaticum and Coptis japonica extracts and to evaluate the antioxidant and anti-inflammatory ability by creating an optimal mixture. Szygium aromaticum and Coptis japonica were extracted with 70% ethanol, 100% methanol, and water to evaluate the antibacterial ability, and it was confirmed that 100% methanol extract of Szygium aromaticum and Coptis japonica water extract had the highest anti-bacterial ability. In addition, when the two extracts were mixed and the anti-bacterial ability was evaluated by ratio, the ratio of 9:1 showed the best activity, and it was confirmed that the antioxidant activity of the mixture was excellent. In Raw 264.7 cells, LPS was used to induce inflammatory responses and confirmed anti-inflammatory activity at 1, 10, 50, and 100 μ g/mL that did not affect survival, and it was confirmed that NO-production inhibition and IL-6 expression inhibition and COX2 and iNOS protein expression inhibition activity were excellent at 10, 50, and 100 μg/mL. Through this study, it is thought that the mixture of Szygium aromaticum 100% methanol extract and Coptis japonica water extract can be used as a natural ing
