Abstract: Garlic (Allium sativum L.) and traditional herb has several functional properties and strong biological activities, making it useful as a functional food material. We investigated the antioxidant and anti-inflammatory activity of mixed compounds from red garlic and supplementary materials, including ginger (Zingiber officinale Roscoe), doraji (Platycodon grandiflorum), quince (Chaenomeles sinensis), citrus peel (Citri Pericarpium), and mint (Mentha arvensis). The extracts were prepared with water (W) and ethanol (E) at 70℃ (W-70, E-70) and 95℃ (W-95, E-95) for 3 h. The total content of phenolic compounds was the highest in E-70 (608.60 mg/100 g). Alliin, one of the active ingredients in red garlic, was contained at 1.18-1.29 mg/g and 0.81-0.85 mg/g in water and ethanol extract, respectively. Another active ingredient of red garlic, S-allyl-cysteine (SAC) had higher content in the water extract than in the ethanol extracts. DPPH radical scavenging activity was higher in E-70 (15.96-73.65%) at 313-5,000 μg/mL. ABTS radical scavenging activity was also higher in E-70 (5.71-77.19%) than in the others. The ROS production rate showed the same tendency as the NO production, with more efficacy in E-95. The expression level of iNOS and IL-1β was decreased in the E-95 significantly at the concentration of 1,000 μg/mL compared to the lipopolysaccharide (LPS) treated group. Based on the above results, the antioxidative and anti-inflammatory activities of the extracts of red garlic and supplementary materials were expressed by different useful substances. The contents of these useful substances were different according to the extraction solvent and temperature.
