Chemical characterization and biological activities of extracts from two plants (Cissus quadrangularis and Acacia polyacantha) used in veterinary medicine in Benin

Abstract

This work focuses on chemical and biological study of two plants, Cissus quadrangularis and Acacia polyacantha used by farmers in Benin in the treatment of salmonellosis in poultry and cattle gastrointestinal diseases from. The results, we note in both plants the presence of several secondary metabolites such as saponins, catechic tannins, mucilages, flavonoids, anthocyanins, reducing compounds, sterols and terpenes. Regarding the polyphenol compounds content, that of Acacia polyacantha is higher than the ones of Cissus quadrangularis. As for the test results of the anti-radical activity, extracts from the trunk bark of Acacia polyacantha show better activity compared to those of C. quadrangularis. The results of antibacterial activity of all (ethanol, hydroethanolic and aqueous) extracts of C. quadrangularis have proven bactericidal towards S. typhi. The ethanolic and aqueous extracts are bactericidal at the concentration of 50 mg / ml while the hydroethanolic extract is bactericidal at 0.78 mg /ml with S. typhi.
