Background : The effective components of Omija(Schisandra chinensis Bailllon) are lignans (schizandrins and gomisins), and this components were contented mostly in seed part on Omija, which have various physiological functionalities such as anti-cancer, anti-inflammatory, and antioxidant activities. Methods and Results : This study was carried out to determine effective condition(CO2, CO2+ethanol) on extraction using supercritical carbon dioxide extraction (SFE) system and to find interrelation on effective components and antioxidant activity of extracts and residues obtained after extraction. Effective components were analysed lignans and phenolic compounds and antioxidant activirty was determined for DPPH radical scavenging ability on methanol extracts of SFE-extract and SFE-residue. On SFE with ethanol, SFE extract was separated two phase, upper(water phase) and lower(oil phase). SFE-extract showed the highest total lignans content(61.36 mg/g, 72.14 mg/g on lower, 50.58 mg/g on upper) and the lowest total phenolic compounds(6.52 mg/100g) and SFE-residue showed the lowest total lignans content(1.45 mg/g) and the highest total phenolic compounds(16.23 mg/100g) by extracted on CO2+ethanol treatment. SFE-residue methanol extract showed the highest DPPH radical scavenging abilities and SFE-extract upper showed the lowest. Conclusion : Thus, this results showed SFE-extract showed the highest total lignans content, but SFE-residue showed the highest DPPH radical scavenging ability although the lowest total lignans content.
