Rice bran is by-product from the dehulling process of rice, an important staple food in Korea. Various studies have been reported immune-enhancing effects of rice bran cultured with Lentinus edodes. In particular black rice bran that contains anthocyanin has the beneficial effects on immune system. SuperC3GHi, a recently released black colored rice cultivar, has higher contents of cyanidine-3-glucoside (C3G), a strong antioxidant than those of currently cultivated black rice cultivars. In this study, we investigate the beneficial effects of fermented SuperC3GHi rice bran (C3G-F) with Lentinus edodes. Using in vivo and in vitro model for inflammation and allgergy, anti-inflammatory and anti-allergic effects of C3G-F were determined. C3G-F induced tumor suppressive effect on Sarcoma-180 cell and B16 melanoma cell injected to mice. These results suggest that the capacity of C3G-F seems to act as a potent immunomodulator and with the absence of notable sideeffects, C3G-F could be used as a novel functional food ingredient having possible therapeutic effects against immunological disorders.
