Evaluation of antioxidant activity, total phenolics and total flavonoids in peels of five cultivars of mango (Mangifera indica) fruit
A comparative studies on the in vitro antioxidant activity of aqueous extracts of peels of five locally available cultivars of ripe mango (Mangifera indica) (Alphonso, Malgua, Rumani, Sindhura and Banisha) fruit has shown that antioxidant properties, total phenolics content (TPC) and total flavonoids content (TFC) differ significantly among selected cultivars. The results indicated that the peels of five types of mango cultivars had considerable amount of antioxidants, phenols and flavonoids, in that the aqueous extract of Sindhura had shown better antioxidant activity (IC 50 of DPPH was 65.34+ 0.62 mg/ml; IC 50 of ABTS was 28.29+ 0.43 mg/ml) and higher TPC (87.38+ 0.43 mg of GAE/g) as well as higher TFC (15.6+ 0.23 mg of QE/g) contents than of the remaining four aqueous extracts of mango fruit peels.
