Abstract
The 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.
