Phytochemicals and Antioxidant Activities

in a linoleic acid system, total phenolic contents (TPC) and bleachability of -carotene in the linoleic acid system.Additionally, the canola oil samples were stabilized with crude concentrated extracts and subjected to ambient aging (6 months).The extent of oxidative deterioration was followed by the measurement of peroxide-, p-anisidine-, conjugated dienes-, and trienes-values.The results of ambient stored samples revealed a significant improvement in these oxidation parameters.The overall order of antioxidant activity of the extracts as determined by various antioxidant assays was determined to be; 80% methanolic extract .100% methanolic extract .80% acetone extracts .100% acetone extract.The results of the present comprehensive analysis demonstrate that extracts of the wheat bran indigenous to Pakistan are a viable source of natural antioxidants and might be exploited for commercial and neutraceutical applications.
