Total Phenolics (TP) including Flavonoids were extracted from eight varieties grown through Conventional and Organic farming system of rice at Norman E. Boralog Crop Research Centre of G.B.P.U.A. & T., Pantnagar (U.K.) India. Extraction of TP including Flavonoids was carried out using 70% (V/V) ethanol at 25ºC. TP and Flavonoid contents were determined using conventional Folin’s and Aluminium chloride tests. Out of eight varieties, Pusa 1121 showed the highest amount of 2, 2- diphenyl-1- picrylhydrazyl (DPPH) scavenging activity followed by Pant Basmati-1 and Pusa 1506 grown through organic farming as compared to conventionally grown rice varieties namely UPR3506-1-1 which offered highest amount of DPPH scavenging activity followed by Tarouri and UPR3488621. Antioxidant activities were found to be directly correlated with the quantity of TP and Flavonoid. TP had the negative correlation with the DPPH scavenging while Flavonoids had the positive correlation with DPPH scavenging activity.
