Abstract

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 side-effects, C3G-F could be used as a novel functional food ingredient having possible therapeutic effects against immunological disorders.

슈퍼자미(SuperC3GHi) 쌀 품종은 색소 성분인 cyanidine-3-glucoside(C3G)의 함량을 크게 증대시킨 품종이다. 슈퍼자미 벼품종을 활용한 새로운 기능성 소재 및 제품으로의 개발 가능성을 타진하기 위하여 본 연구에서는 슈퍼자미 벼품종의 버섯 균사체 발효물을 이용하여 항염증, 항알러지, 항암 기능의 검증을 수행하였다. 1. 슈퍼자미 미강 발효물의 항염 활성을 분석하기 위하여 ear-edema test를 수행한결과 약 35.6%의 염증 억제율을 나타내었다. 2. 슈퍼자미 미강 발효물의 항알러지 활성을 확인하기 위하여 비만세포인 RBL-2H3 세포의 hexoamidase 및 histamine 유리 활성을 조사한 결과 슈퍼자미 미강 발효물을 처리하였을 때 각각 약 40% 및 57%의 억제 활성을 나타내어 항알러지 활성을 확인하였다. 3. 슈퍼자미 미강 발효물의 항암 활성을 조사한 결과 복수암 모델 및 고형암 모델에서 모두 암세포의 증식을 억제하는 활성을 나타내었고, 혈액중 백혈구의 수치를 유의적으로 증가하는 것으로 나타나 슈퍼자미 미강 발효물이 항암 활성을 있음을 확인 할 수 있었다. 4. 이상의 결과에서 슈퍼자미 품종의 미강을 버섯 균사체 발효를 통해 얻어진 기능성 소재는 항염, 항알러지, 항암 활성을 통해서 우수한 기능성 소재로서의 개발 가능성이 매우 높다고 판단된다.
