Abstract
Aim: Hyptis suaveolens is well known for its immense medicinal properties and are beneficial as folk medicine. The objective of the study is to investigate the efficacy of the leaves for it antimicrobial activity.
Material and Methods: The leaves of Hyptis suaveolens was subjected to extraction process using n-hexane, ethanol and distilled water as solvents and the antimicrobial activity was analyzed against different bacterial strains viz.; Escherichia coli, Proteus mirabilis, Streptococcus pneumoniae, Staphylococcus aureus, Klebsiella aerogenes, Pseudomonas aeruginosa, Salmonella typhi, Enterococcus faecalis by agar well diffusion method.
Results: Aqueous extracts showed inhibitory effect against the different tested bacteria organisms with variable zone of inhibitory range 6 -21 mm.
Conclusion: The aqueous extracts of Hyptis suaveolens exhibited the presence of highly effective bio-active compounds in these extracts. These can further be evaluated and characterize to improve upon what has been done to create a novel compound that can be useful for various medicinal purposes.
