Antioxidant and anti-adipogenic effects of kohlrabi and radish sprout extracts

초록

Common cruciferous vegetables, kohlabi (Brassica oleracea) and radish (Raphanus sativus), contain phytochemicals such as glucosinolates and carotenoids. Therefore, this study investigated the antioxidant and antiadipogenic effects of kohlrabi sprout extract (KSE) and radish sprout extract (RSE). The total carotenoid and glucosinolate contents of KSE and RSE were 39.50±0.67 and 76.73±2.75 mg/g, respectively. The total glucosinolate contents of KSE and RSE were 2.65±0.02 and 8.13±0.54 mg/g, respectively. The in vitro-antioxidative activities of KSE and RSE were significantly increased in a dose-dependent manner. Furthermore, β-carotene and glucosinolate-enriched KSE and RSE significantly inhibited lipid accumulation and reactive oxygen species production during the adipogenesis of 3T3-L1 preadipocytes. These results suggest that glucosinolate-enriched KSE and RSE, especially RSE, can be used in the treatment of obesity and as a natural source of antioxidants. ©The Korean Society of Food Science and Technology
