The Active Compounds in Equisetum arvense L. and their Inhibitory Effects on Growth of Some Pathogenic Bacteria

Abstract

This research has been performed on the vegetative parts of the

Horsetail Equisetum arvense L.  v.ilich  grows    naturally  in  Haj Umran , north    of   Iraq , to determine and estimate some   active chemical    compounds ,  besides   studyi ng  their inhi bitory  effe(;tS upon    some  urinary  tracts infections (UTI) bacteria    through  the

investigation on the  inhibitory effects of water and ethanolic extracts of this plant .

The results revealed presr.:nr.:t: of some active chemical compounds   such as: tannins, saponins, resins, flavonoids and glycosides. The    ethanolic  extracts    has   an inhibitory effect upon UTI   bacteria    (gram+ve & gram-vc)  according  to   agar      well

diffusion method. Proteus mirabi/is and  Pseudomonas  aeruginosa

were more sensitive than Staphylococcus aureus  and  Klebsiella spp.
