Antibacterial activity of various extracts of leaf and wood of Anisomeles malabarica

Water is essential to life, but many people do not have access to clean and safe drinking water and many die of waterborne bacterial infections. Antibacterial properties of various extracts of Anisomeles malabarica (L) were investigated against both clinical and laboratory isolates of bacteria using the disc diffusion method. Aqueous extracts (10 mm zone diameter of inhibition, MIC 10µg/mL) demonstrated the highest activity, followed by Ethanolic extract (8 mm zone diameter of inhibition, MIC 20µg/mL) methanolic extract demonstrated the least activity against the test bacteria (4 mm zone diameter of inhibition, MIC 40 µg/mL). Generally the antibacterial activities of Anisomeles malabarica are comparable to that of standard oflaxcin to a certain extent. Finally, these results suggested that Anisomeles malabarica (L) can be used to source antibiotic substances for possible treatment of bacterial infections and for the development of new drugs.
