초록

본 연구에서는 등수국 잎 추출물의 항염 및 항균 활성을 확인하고 유효성분을 분리하여 화학구조를 동정하였다. RAW 264.7 세포를 이용한 항염 활성 실험 결과, n-hexane (Hex) 및 ethyl acetate (EtOAc) 분획물이 세포 독성 없이 nitric oxide (NO)의 생성 및 iNOS 단백질의 발현을 농도의존적으로 억제시키는 것을 확인하였다. 추가적인 항염 기전 연구 결과, n-Hex 및 EtOAc 분획물이 전염증성 cytokine (TNF-α, IL-1β, IL-6)의 생성을 억제하는 것을 확인하였다. 또한 표피포도상구균과 여드름균을 이용한 활성 실험 결과, 추출물 및 n-Hex, EtOAc, n-butanol (BuOH) 분획물에서 항균 활성이 나타났다. n-Hex 및 EtOAc 분획물의 활성 성분을 규명하기 위해 컬럼 크로마토그래피를 수행하여 4 개의 화합물을 분리하였다; phytol (1), corosolic acid (2), asiatic acid (3) 및 1-O-p-coumaroyl-β-D-glucopyranoside (4). 이들 화합물은 모두 등수국에서 처음으로 분리된 물질이다. 또한 HPLC 분석을 통해 등수국 잎 추출물에서 분리된 화합물의 함량을 측정한 결과 phytol (1) 이 27.8 mg/g 함유되어 있는 것으로 확인되었다. 이상의 연구 결과를 바탕으로 등수국 잎 추출물을 이용한 항염 및 항균 효과를 갖는 천연 화장품 소재로의 개발이 가능할 것이라 사료된다.

In this study, the anti-inflammatory and anti-bacterial activities of the extracts from the leaves of the Hydrangea petiolaris were identified, and the chemical structure was identified by separating the active ingredient. As the result of the anti-inflammatory activity experiment using RAW 264.7 cells, it was confirmed that the n-hexane (Hex) and ethyl acetate (EtOAc) fractions inhibited the production of nitric oxide (NO) and the expression of iNOS protein in a concentration-dependent manner without cytotoxicity. In addition, the n-Hex and EtOAc fractions reduced the production of pro-inflammatory cytokines (TNF-α, IL-1β and IL-6). Upon the anti-bacterial tests using Staphylococcus epidermidis and Cutibacterium acnes, the extract, n-Hex, EtOAc and n-butanol (BuOH) fractions showed potent activities. In order to isolate the active constituents, the n-Hex and EtOAc fractions were further purified to afford four phytochemicals; phytol (1), corosolic acid (2), asiatic acid (3) and 1-O-p-coumaroyl-β-D-glucopyranoside (4). All of the compounds 1 - 4 were isolated for the first time from this plant. In addition, the contents of isolated compounds were determined by HPLC and the quantity of phytol (1) was 27.8 mg/g for the 70% EtOH extract. Based on the above research results, it is believed that it will be possible to develop a natural cosmetic material that has anti-inflammatory and anti-bacterial effects using the extract of H. petiolaris leaves.
