DETERMINATION OF PHENOLIC COMPOUNDS AND ANTIOXIDANT ACTIVITY OF WHITE HENBANE (HYOSCYAMUS ALBUS L.) PLANT TREATED BY KINETIN (K)AND 2,4-DICHLOROPHENOXYACETIC ACID (2,4-D) IN MILA, ALGERIA
Keywords:Hyoscyamus albus L., phenolic compounds, antioxidant activity, K, 2, 4-D.
AbstractThe present work deals with the evaluation of the antioxidant activity of the extracts of the white henbane ( Hyoscyamus albus L.) of the solanaceae family, treated with phytohormones 2,4-Dichlorophenoxyacetic acid (2, 4-D) andKinetin (K)in doses 0, 10,20mg / l), widely used in traditional medicine and very rich in alkaloids. Preliminary phytochemical screening showed that treatment with phytohormones had no effect on the quality of the secondary metabolites. The results of the phytochemical study of the plant showed that the treatment with 2,4-D and K had a significant effect by reduction compared to the untreated plant on the phenolic compounds studied. The evaluation of the antioxidant activity in vitro was investigated by the DPPH trapping method and showed that the treatment with 2,4-D and K had a significant effect on the antioxidant activity so all the extracts of the various treatments of H. albus can act as radical scavengers.
