Abstract

The phytochemical review conducted on the aerial part Ammoides verticillata has revealed the presence of six chemical families: flavonoids, tannins; gallic tannins, anthocyanins and the coumarins, cateichic tannins. The aqueous extract of the Ammoides verticillata could bring back the stable free radical 2,2-diphenyl-1-picrylhydrazyl (DPPH) to the yellow-colored diphenylpicrylhydrazine with an IC50 of 0.020 mg.mL-1. It is gifted with antioxidant activity, however it was less effective than vitamin C (0.001 mL-1). The essential oil of the Ammoides verticillata has presented a strong antimicrobial activity against Gram negatif germs targets of original clinical action: E. coli (ESBL) (37 mm), E. coli (39.5 mm), Klebsiella pneumoniae (36.5 mm) and especially with the yeast: Candida albicans ATCC 10231 (47 mm) and Saccharomyces cerevisie ATCC (42 mm), which are highly sensitive to the oil inhibitory action. However, the oil has presented a low activity against the bacteria P. aeruginosa (12.5 mm).
