The Effect of Watery & Alcoholic Plant Extracts of Elettaria cardamomum On Growth of Some Bacteria Isolated from Otitis media Infections

Abstract

This study was done to determine the effect of watery and alcoholic extracts of Elettaria cardamomum  on growth of bacteria isolated from Otitis media Infections which are : Pseudomonas aeruginosa , Staphylococcus  aureus and  Klebsilla   spp.        The biochemical analysis revealed that watery extracts of Elettaria cardamomum  contains: Glycosides,  Alkaloids, Saponines, Tannins, and Volatile oils, ( This compound is Soluble in water ) , while the alcoholic extracts contains : (in addition to the above mentioned compounds ) Phenols , Resins , Flavonids and Coumarins. ( This compound is  Soluble in organic solutions ).      To study the effect of watery and alcoholic extracts of Elettaria cardamomum  on growth of bacteria isolated from Otitis media Infections, we make four extracts ( cold watery  extract , hot watery extract , cold alcoholic extract and hot alcoholic extract.     The study shows  that (hot alcoholic extract ) was more effective than the other extracts, by using agar diffusion method (wells).  The study also showed that staphylococcus  aureus ( gram positive ) bacteria is more sensitive to plant extracts than the gram negative bacteria , while Pseudomonas aeruginosa  was more resistant to plant extracts than the others.
