This study was aimed to compare the antioxidant and cytoprotective effects of hot‐water and enzyme‐extracted constituents of Protaetia brevitarsis seulensis powder. The products of enzymatic extraction had 1,1‐diphenyl‐2‐picrylhydrazyl (DPPH)‐radical‐scavenging activity, cytotoxic effects, and provided cytoprotection against H2O2 and intracellular reactive oxygen species. Enzymatic extraction improved DPPH‐radical‐scavenging activity relative to hot‐water extraction (P < 0.05), with inhibition rates of 33% at 500 μg/mL and 35% at 1000 μg/mL. Cell viability ranged from 100 to 122%, and was higher for hot‐water than for enzymatic extraction (P > 0.05). Hot‐water extraction achieved greater cytoprotection against H2O2 than enzymatic extraction. However, enzymatic extraction achieved greater antioxidant and cytoprotective activity against reactive oxygen species than hot‐water extraction. These results provide evidence of the antioxidant and cytoprotective effects produced by enzymatic extraction of the active ingredients from Protaetia brevitarsis seulensis powder.

Abstract: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.
