The study of Antimicrobial Effect of pineapple Extract

Recently more attention pharmacological researches have been done on Replacement medical plants instead of chemical drugs، so in this research antimicrobial properties of aquatic and ethanolic extracts (80%) of pineapple، on Staphylococcus. aureus، Bacilluss. anthracis، E. coli، Pseudomonas. aeroginosa، by using streak culture، using routine methods، appling the Muller-Hinton Agar، punch well method and measuring the diameter of inhibitory zone were studied. The aquatic and ethanolic extracts (80%) in 0. 1 g/ml concentration have been showed remarkable antimicrobial effect on Staphylococcus. aureus، Bacilluss. anthracis. Although antimicrobial effect of E. coli، Pseudomonas. aeroginosa have been lessthan others. The higher antimicrobial effect on ethanolic extracts (80%) were belong to stem ethanolic extracts with 17 mm diameter of inhibitory zone and then for leaf ethanolic extracts with 18 mm diameter of inhibitory zone. various study have been show that pineapple is full of bromelain، Ca، K،fiber and other vitamins that have made ability for antimicrobial activity -antibiotic effect، antimetastatic effect. The result show that the effect of leaf، stem pineapple extracts seams that because of having higher value of these mentioned materials، have more effects. Among of the results، the best results was for ethanolic leaf extracts on Bacilluss. anthracis. As a result extracts of this plant could be suggested as a potential source for drugs.
