تقييم فعالية مستخلصات نبات الزنجبيل Zingiber officinale Rosc. المضادة لبعض أنواع البكتريا المرضية

Abstract EN

This research has been performed to assess the antibacterial efficiencies of the crude extracts of dried rhizome powder of Zingiber officinale plant.

These extracts were obtained by using different organic solvents and water. Results revealed that diethylether and ethanolic extracts have shown an inhibitory action upon both Gram positive and Gram negative bacteria in concentrations between (10–100) mg/ml. Cold water extracts showed higher inhibitory activity than that of the hot water extract.

These results obtained by using the well diffusion method.

In addition all these results were comparised with some classical antibiotics such as Erythromycin, Amoxycillin, Ampicillin and others.

The extracts showed higher inhibitory activity than these antibiotics were used except the extract which was obtained by hot water.
