Schisandra chinensis (Turcz.) Baill., which is known as omija in South Korea, is mainly cultivated in East Asia. The present study aimed to investigate the chemical composition of essential oil from the omija (OMEO) fruit obtained by supercritical fluid extraction using CO2 and to confirm the antioxidant and anti-inflammatory activity of OMEO using HaCaT human keratinocyte and RAW 264.7 murine macrophages. As a result of the chemical composition analysis of OMEO using gas chromatography-mass spectrometry, a total of 41 compounds were identified. The detailed analysis results are sesquiterpenoids (16), monoterpenoids (14), ketones (4), alcohols (3), aldehydes (2), acids (1), and aromatic hydrocarbons (1). OMEO significantly reduced the increased ROS levels in HaCaT keratinocytes induced by UV-B irradiation (p < 0.05). It was confirmed that 5 compounds (α-pinene, camphene, β-myrcene, 2-nonanone, and nerolidol) present in OMEO exhibited inhibitory activity on ROS production. Furthermore, OMEO showed excellent anti-inflammatory activity in RAW 264.7 macrophages induced by lipopolysaccharide. OMEO effectively inhibited NO production (p < 0.05) by suppressing the expression of the iNOS protein. Finally, OMEO was investigated for exhibition of anti-inflammatory activity by inhibiting the activation of NF-κB pathway. Taken together, OMEO could be used as a functional food ingredient with excellent antioxidant and anti-inflammatory activity.

Supercritical fluid extraction (SFE) was used for the extraction of phenolic compounds from peach blossom (Amygdalus persica). The optimum conditions of SFE were optimized by response surface methodology and confirmed at 64°C, 30 MPa, 143 min, and 35 mL ethanol (100%) as modifier for maximum total phenolic contents (54.10 mg GAE g−1 DW), which was higher than the yield achieved by ultrasonic-assisted extraction (44.04 mg GAE g−1 DW). The antioxidant activities and tyrosinase inhibitory activities of extraction extracted by SFE were 79.55% and 14.42%. Furthermore, chlorogenic acid, quercetin-3-O-galactoside, kaempferol-3-O-galactoside, quercitrin-3-O-rhamnoside, and kaempferol 4′-glucoside were identified in this study.
