Abstract

Black colored rice has long been consumed in Oriental countries and is considered to be a healthy food. Extracts from rice with three different colors (white, black, and green) were prepared by using 80% MeOH and subjected to biological screening activities. The levels of antioxidative activity of black colored rice cultivars such as C3GHi and Heugjinjubyeo in radical scavenging activity were higher than those of the related white and green rice ones. When the effect of the extracts on thrombin time inhibition was analyzed, the extract from Heugjinjubyeo showed a dose-dependent suppressive activity. In addition, all the extracts tested did not inhibit the cyclooxygenase activity. Therefore the health benefits of the colored rice are attributed in part to their unique phytochemical composition such as high level of anthocyanin pigments with other minor strong antioxidant components for potential use in neutraceutical or functional food formulations.
