Abstract
Abstract Description of the subject: Evaluate the phytochemicals and antioxidant activity of the peels, flowers and seeds of Opuntia ficus-indica L.. Objective : Valorization of bioactive compounds of cactus pear from Sidi Fredj (Souk-Ahras, Algeria). Methods : Various organic extracts of the three parts of the plant have been the subject to determine the content of total polyphenols, flavonoids and betalains as well as a study of their antioxidant activities by DPPH test, FRAP and by phosphomolybdenum test (TAC). Results : Quantitative analysis of phenolic compounds showed that flower extracts have the highest content of phenolic compounds and flavonoids. In addition, the peels have a high content of betalains. As for the evaluation of antioxidant activity, the flowers and seeds showed considerable DPPH free radical scavenging power. On the other hand, the peel extracts revealed an important total antioxidant capacity and a consequent ferric iron reducing power. Conclusion : Opuntia ficus-indica peels, flowers and seeds are rich in antioxidants and hold high antioxidant activity.
