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.
