Considering nutraceutical potentiality of phytochemicals, a few indigenous red rice germplsams of Assam, India were analysed for various phytochemicals, antioxidant activities and a few mineral contents. Among the sixteen germplasm analysed in their brown form, the total phenol content, total flavonoid content, and the anthocyanin content per100 gm dry matter ranged mg± (‘Ranga Dariya’) to 2223 mg± (‘Amana Bao’), ± (‘Ixojoy’) to ± (‘Dal Bao’) and ± µg (‘Kolaguni’) ± µg (‘Betu’), respectively. For the polished form of rice, the same in 100 gm dry matter ranged mg± in ‘Ranga Dariya’ to 1409 mg± in ‘Kolaguni’, from ± mg in ‘Ranga Dariya’ to ± in ‘Negheribao’ and from ± (‘Biroi’) to ± (‘Hurupibao’), respectively. The antioxidant activities were observed to be the highest ± in ‘Negheribao’ (for brown form of rice) and ± in ‘Kenekuabao’ (for polished form of rice) and the lowest ± in ‘Betu’(for brown form of rice) and ± % in ‘Ranga Dariya’ (polished rice), respectively. In brown rice, on dry weight basis, the iron, zinc and manganese content ranged from mg per 100 gm, mg to per 100 gm and mg per 100 gm to mg per 100 gm, respectively. The study revealed some indigenous rice germplasm of Assam, India which are significant considering phenolic compounds and mineral content. | A study on phytochemicals and mineral content of indigenous red rice of Assam, India
