Abstract:
Eleven mothbean varieties including both pre-released and released varieties were procured from AICRP for dry land agriculture, Regional Agricultural Research Station, Vijayapur, University of Agricultural Sciences, Dharwad and they were analyzed for proximate composition, antioxidant activity and total polyphenol content. RMB-141 had highest crude protein, KBMB-1 had highest crude fiber, MBS-27 had higher moisture content, BGMBG-10 had higher fat content, RMB-101 had highest carbohydrate content, CGM-18 had highest fat content. There was significant difference (p≤0.01) between the two groups with regard to antioxidant activity and total phenolic content. Antioxidant activity ranged from 10.57-13.44 percent. Highest antioxidant activity was observed in the variety RMB-408 (13.44%). The total polyphenol content varied from 2.28-2.79 mgGAE/g where RMB-408 had highest content (2.79 mgGAE/g). The variation in the proximate composition between the varieties could be from location, varietal differences, soil and agroclimatic condition. The reason attributed to higher phenolic content is may be due to dark color of the seed and phenolic compounds are concentrated in the seed coat region and this is further related to higher antioxidant activity.
