Evaluation of Antimicrobial Activity of Annona reticulata Linn. Bark and Seeds

The present study aims to determine the antimicrobial activity of Annona reticulata Linn. Aqueous and ethanolic extracts of bark and seeds were used at concentrations 10, 12 and 14 mg/ml. All the extracts were screened for the antimicrobial activity against Gram positive and Gram negative bacteria. Agar cup method was selected for the determination of antimicrobial activity. The screening results showed that the aqueous and ethanolic extracts of bark and seeds of Annona reticulata were found to be effective against Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa. None of the extract showed antimicrobial activity against Salmonella abony. The study suggests that the stem bark and seeds of Annona reticulata are promising in the development of phytomedicine of antimicrobial properties.
