Characterizes the Antioxidant Activity of Recombinant Inbred Rice Lines Derived from Traditional Kavuni and CO 50

Abstract

The present study aimed at investigating the antioxidant activity of traditional black Kavuni, CO 50, and their Recombined Inbred Lines. The total antioxidant assay was carried out in twenty-five rice samples. Hydroxyl radical scavenging activity, Superoxide radical scavenging activity, Nitric oxide radical scavenging activity, and total antioxidant activity were assessed by traditional black Kavuni, CO 50 and 145-3 Recombined Inbred Line by using standard procedure. The highest percentage of inhibition was observed in black color rice samples, which ranged from 51 to 83 percent. The 145-3 Recombined Inbred Line and kavuni had the highest antioxidant activity. In Hydroxyl radical scavenging activity, Superoxide radical scavenging activity, Nitric oxide radical scavenging activity, and total antioxidant activity, the highest inhibition was observed in methanolic extract of Kavuni parent and selected 145-3 Recombined Inbred Line.
