This study was designed to analyze the chemical compositions of ‘Setoka’ branch essential oils (SEBO) and to test their biological activities. ‘Setoka’ is a Citrus species widely cultivated in Jeju Island. At the present, ‘Setoka’ branches produced by thinning process were mostly discarded as a waste. Therefore, utilization of this branch waste has received much attention. ‘Setoka’ branch essential oils (SBEO) were prepared by treatment of its ethanol extracts with jojoba oil. SBEO were chemically analyzed using gas chromatograph-mass spectrometry (GC-MS), and following components were identified; ethyl linoleate (64.14%), ethyl palmitate (16.50%), neophytadiene (11.06%) and beta-citronellol (5.09%). The anti-inflammatory activity in the SBEO was examined using RAW 264.7 murine macrophage cells stimulated with LPS. As a result, the SBEO inhibited nitric oxide (NO) productions with a dose-dependent manner. In addition, SBEO showed good anti-microbial activities against drug-susceptible and -resistant skin pathogens such as Staphylococcus aureus and Propionibacterium acnes, which are acne-causing bacteria. Based on these results, we suggest that SBEO has the possibility for use as an anti-inflammatory and anti-microbial agent in cosmetic applications.
