摘要：Buckwheat is a precious source of various bioactive compounds like phenolics, flavonoids, rutin, and quercetin, etc. This research work was performed to harvest the nutraceutical potential of indigenous buckwheat varieties and their milling fractions (fine flour, coarse flour, bran flour, and husk). Common buckwheat (CBW) and Tartary buckwheat (TBW) were analyzed in terms of total phenolic content (TPC), total flavonoid content (TFC), and DPPH scavenging activity. When compared to common buckwheat, Tartary buckwheat had a higher total phenolic content (2101.421 mg GAE/100 g), total flavonoid content (1233.990 mg QEQ/100 g), and DPPH scavenging activity (44.51%).In the same context, throughout comparisons among milling fractions, the highest TPC and TFC were observed in the husk part of Tartary buckwheat while the lowest was found in common buckwheat. During the comparison of different solvents and their concentrations, it was observed that Ethanol 70% extracted a greater quantity of phytochemicals as compared to the rest of the other solvents and concentrations. This study recognized variability among buckwheat varieties and milling fractions for nutraceutical potential and nutritional qualities that can be used in the treatment of different maladies and food products.`.
