Antioxidant capacity of diverse Indian cultivars of Pigeon pea
The pigeon pea with the scientific name Cajanus cajan. It is referred as perennial legume crop from the Fabaceae
family. Antioxidants are the essential nutrient component for our health. They fight against reactive oxygen species (ROS) or
free radicals before it acts upon the cells. There are different laboratory assays which help in determination of antioxidants
such as ABTS (2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid)), Superoxide radical scavenging assay, condensed
tannin content. Highest condensed tannin contents were observed for DPL variety while lowest was observed NDA variety.
The results indicate that pigeonpea seeds are rich in antioxidant activity. Superoxide radical has a low reactivity and a low
capacity to penetrate the lipid membrane layer, but it can generate hydrogen peroxide and highly reactive hydroxyl radical.
The sample extracts exhibited significant superoxide radical scavenging activity. The assessment of antioxidant potential
might be a fruitful approach for advocating them as nutraceuticals.
