Abstract: | Polyphenoles are plant’s secondary metabolites that have been largely studied last years. The objective of this study was to evaluate the impact of a habitual heat process on the content of polyphenols and flavonoids in a cereal crop that grows in Adrar region, called pearl millet or Pennisetum glaucum. The objectif of this study is to evaluated the heat traitement . The antioxidant activity of different phenolic compounds of treated seeds was evaluated by the method of DPPH. Our results showed that heat traitement rose the pourcentage polyphenols to 43 .27%. Also, flavonoids to 38.29%. The antioxidant activity of different extracts (evaluated by the method of trapping free radical DPPH●) has revealed that roasted seeds exhibited, at high concentrations, a high antioxidant capacity which were compared with standard (Gallic acid -Vitamin C). |
