Abstract

Aqueous, methanol, chloroform and petroleum ether extracts of leaves and seed powder of Aegle marmelos obtained through soxhlet extraction process were qualitatively tested for presence of active principles and in-vitro antibacterial activity. Terpenoids were found to be present in all leaf extracts while tannins were absent. In all seed extracts, flavonoids and terpenoids were absent while phenols and alkaloids were present except in chloroform. Antibacterial activity was tested by agar well diffusion method. All leaf extracts, concentrated and diluted (1:3) showed substantial antibacterial activity against Escherichia coli, Staphylococcus aureus, Salmonella typhi and Pseudomonas aeruginosa. Pseudomonas aeruginosa was not inhibited by diluted chloroform extract. Seed extracts also showed antibacterial properties in concentrated as well as diluted form. Aqueous extract and chloroform extract in diluted form did not showed any action on Pseudomonas aeruginosa. Potential applications of Aegle marmelos in treatment of skin infections are discussed.
