Antimicrobial activity of alcoholic and aqueous extracts of Corchorus olitorius leaves and seeds against some pathogenic bacteria and yeasts.
Abstract
The present study describes the antimicrobial activity of methanol and aqueous
extracts with four concentrations of each one (50,100,200,400) mg/ml of Corchorus
olitorius leaves and seeds were estimated against some types of pathogenic bacteria
(Staphylococcus aureus, Bacillus cereus, Enterococcus faecalis, Escherichia coli,
Salmonella typhi , Proteus vulgaris ) ,also against some yeasts (Candida albicans,
Saccharomyces boulardii ,Saccharomyces cerevisiae), by using agar-well diffusion
assay. All extracts exhibited varying degree of antimicrobial activity against the tested
bacteria and Candida albicans, and this activity was increased with the increasing of
concentrations belongs to them , while Saccharomyces boulardii and Saccharomyces
cerevisiae showed resistance against all extracts .All alcoholic extracts (of leaves and
seeds) exhibited higher degree of antimicrobial activity than the aqueous, also
alcoholic and aqueous extracts of plant seeds exhibited higher degree of antimicrobial
activity than the alcoholic and aqueous extracts of Corchorous olitorius leaves.
