The inhibitory effect of alcoholic extracts from the leaves, aerial parts and roots of Corchorus olitorius L. (Molukhiya), on some pathogenic bacterial species


In this study, the preparation of alcoholic extracts of leaves, aerial parts, and roots of the plant Corchorus olitorius L. in powder form have been prepared in different concentrations consisted of (30, 50, 70) mg/ml. Extracts were used to detect the inhibitory activity on gram’s negative and gram’s positive pathogenic bacteria, which include the following types: Klebsielle pneumoniae, Escherichia coli, proteus mirabilis, Serratia marcescuns, Aeromonas hydrophila Staphylococcus aureus and Streptococcus fecalis. The results of the inhibitory activity of alcoholic extracts depending on the different types of bacteria, and there was a clear increase in the rate of inhibition range with increasing the concentration of plant extracts against bacteria, All concentration of extracts were found to exhibit significant differences at level (p<0.05) by antimicrobial activity against most bacterial species. Also the results showed significant differences among the alcoholic extracts of the leaves, aerial parts and roots extracts on the growth of some types of bacteria at level (p<0.05).
