Activité biologique des extraits aqueux d’Ammodaucus leucotrichus Cosson & Durieu.

Abstract

Ammodaucus leucotrichus a medicinal plant belongs to the Apiaceae family. This species known as the «Oum drayga» is very little studied. For this, the main objective of this study is to determine the power of the aqueous extracts of these species to set the free radicals, reduce ferric iron and to inhibit the growth of certain microbial strains. The extraction of active ingredients is performed by traditional preparation methods of the plant in the traditional pharmacopoeia which are: the decoction, infusion and maceration. The active ingredients dosed are total phenolic contents, flavonoids, phenolic acids and condensed tannins. Evaluation of antioxidant activity is made by the use of three tests which are: Test ABTS, DPPH test and measurement of FRAP reducing power. The antimicrobial sensitivity of different extracts was assessed by disk diffusion method on three bacterial strains Escherichia coli, Proteus mirabilis et Micrococcus luteus.
