    본 연구에서는 일반 메밀과 쓴 메밀의 제분 분획 별(겉껍질, 겨, 가루) 에탄올 추출물의 항산화 성분 함량을 분석하고, 항산화 활성을 시험관과 세포 수준에서 확인하였다. 그 결과, 일반 메밀보다 쓴 메밀에서 총 폴리페놀 및 총 플라보노이드 함량이 월등히 높았으며, 항산화 물질로 주된 성분은 루틴으로 확인되었고, 에탄올 추출과정에서 루틴이 퀘세틴으로 일부 분해되는 것으로 나타났다. 또한 식용 부위인 가루 분획보다 겨 분획에서의 항산화 성분 함량이 높은 것으로 분석되어 겨 분획의 항산화 기능성 소재로 개발의 필요성을 제시하였다. 한편 시험관 및 세포수준에서 항산화 효과를 확인한 결과, 일반 메밀보다 쓴 메밀에서의 항산화 활성이 유의적으로 높았으며, 특히 쓴 메밀 겨 분획의 항산화력이 우수한 것으로 나타났다. 메밀 추출물을 산화스트레스 유발 전, 후 처리한 경우 모두에서 항산화 활성이 유사한 경향으로 나타나, 메밀 추출물의 산화스트레스 예방 및 치료 효과 가능성을 제시하였다.


    The objective of the current study was to evaluate the antioxidant activity of ethanol extracts from common and tartary buckwheat milling fractions (hull, bran, and flour). The results indicated that total polyphenol and flavonoid contents were higher in tartary buckwheats than in common buckwheats, which was related to high rutin levels. In particular, the highest rutin content was detected in the bran fraction. ABTS and DPPH radical scavenging activities of tartary buckwheats were higher than those of common buckwheats, especially in bran. Cellular antioxidant activity of tartary buckwheat milling fractions was more pronounced than that of common buckwheat in both Caco-2 and Raw 264.7 cells, demonstrating the higher cellular antioxidant effect of tartary buckwheat bran. The cytotoxic effect of both common and tartary buckwheat milling fractions on cell proliferation was not significant. These results suggest that tartary buckwheat bran may have much potential for usefulness in protective and therapeutic antioxidant applications.
