영문 초록

This study was carried out to investigate the antioxidative and anti-inflammatory activity of crude anthocyanin compounds extracted from black soybean. The crude anthocyanin compounds were extracted with 80% methanol and concent-rated to powder. The most abundant compound isolated from the extract was C3G(cyanidin-3-glucoside). The superoxide dismutase (SOD) assay was conducted to assess the antioxi-dative activity of the crude extract. SOD, which catalyzes the dismutation of the superoxide anion into hydrogen peroxide and molecular oxygen, is one of the most important antioxi-dative enzymes. The black soybean anthocyanin extracts in-hibited more than 90% of the superoxide radical at a concent-ration of 0.1% and 100% at a concentration of 0.5%, indicating that this extract displayed excellent antioxidative activity. To assess the anti-inflammatory activity of the extract, a NO(Nitric oxide) production assay in RAW 264.7 cells was performed. NO is an important physiological messenger and effector molecule in many biological systems, including immunological, neuronal and cardiovascular tissues. In this assay, the anthocyanin extracts showed a high anti-inflam-matory potential, where the inhibitory potency for NO pro-duction was similar to the positive control, particularly for EGCG(epigallocatechin-3-gallate), which is known to have excellent anti-inflammatory activity. Thus, it can be concluded that the anthocyanin extracts from black soybean have distinctive pharmaceutical activities and may be used as an excellent source materials to supplement the health benefits of various food products.
