Antioxidative and antiproliferative activities of ethanol extracts from pigmented giant embryo rice (Oryza sativa L. cv. Keunnunjami) before and after germination

BACKGROUND/OBJECTIVES Oxidative stress is a major cause of cancer. This study investigated the effects of the ethanol extracts from germinated and non-germinated Keunnunjami rice, a blackish-purple pigmented cultivar with giant embryo, on selected human cancer cell lines and on the antioxidant defense system of mice fed with a high-fat diet.
