PHYTOCHEMICAL STUDY AND EVALUATION OF THE ANTIOXIDANT ACTIVITIES OF LEAVES FROM VERNONIAAMYGDALINA

The aim of this study is to highlight the phytochemical composition and antioxidant potential of the ethereal extract of the leaves of Vernoniaamygdalina, a plant used in traditional medicine in Côte dIvoire.Phytochemical studies using TLC and LC-MS revealed, in addition to coumarins, flavonoids and phenolic acids. Determination of the antioxidant potential by TLC and spectrophotometry using the DPPH radical showed the antioxidant power of Vernoniaamygdalina leaves with a CR50 of 0.01995 ± 0.2x10-5 % mg/mL.The many pharmacological properties of V. amygdalina would therefore depend on the coexistence of these phytocompounds.
