A study on antimicrobial activity of ethanolic extract from stem barks of Aegle marmelos

Abstract

Now days some synthetic formulations developing a tolerance in children and adults and the causative organisms becomes more resistant to usage of synthetic formulations. We can overcome this resistance by use of medicinal plants. We taken extract of Aegle marmelos with 90% Ethanol, 72 hrs of cold extraction. It gives antimicrobial activity. We have tested this activity against Escherichia coli, Aspergillus niger, Bacillus cereus, Klebsiella pneumoniae. The Experiment was performed by two methods viz. Disc-diffusion method and Cup-plate method. The Antimicrobial activity Aegle marmelos may be due to presence of marmin and fagarine. This results gives assurance that bael bark has significant antimicrobial activity.
