The Inhibitory Effects of Volatile Oils and Flavonoids Extracted from Aerial Parts of Teucrium polium on the Growth of a Number of Pathogenic Microorganism

This study include the determine the inhibitory effects of aqueous, alcoholic, volatile oils and flavonoids extracted from aerial parts of Teucrium polium on the growth of a number of pathogenic bacteria including Staphylococcus aureus, Proteus vulgaris, Escherichia coli, Pseudomonas aeruginosa, Streptococcus pyogenes. The results indicated that the ethanol extract and the ethyl acetate extract of the Teucrium polium showed high inhibitory effect compared to other extracts against Pseudomonas aeruginosa and Staphylococcus aureus, using Erythromycin and Cephalexin as a standard antibiotics, while the volatile oil showed moderate inhibitory effect against Pseudomonas aeruginosa and Staphylococcus aureus, in comparison with Cephalexin, while the water extract did not show any inhibitory effect against the bacteriaused in this study.
