Evaluation of TLC antioxidant activity and pytochemical screening of leaf extracts of Dischistocalyx Hirsutus C. B. Clarke

Abstract

The study of phenolic compounds remains an area of the future because of the antiviral, antitumor, anti-inflammatory, anti-allergy, anti-cancer, healing, antiseptic and antioxidant properties they possess. The aim of our study was to evaluate the antioxidant activity and to evaluate the phytochemicals from the extracts (aqueous, hydroethanolic and ethanolic) of the leaves of Dischistocalyx hirsutus (Acanthaceae), a plant of the Congolese pharmacopeia. Our study showed the presence of several families, namely anthocyanins, flavonoids, tannins, cardiotonic heterosides and saponins. The presence of these different chemical families is more marked with the hydroethanolic extract. The TLC analysis by DPPH revealed the antioxidant potential of the extracts.
