IN VITRO ANTIBACTERIAL ACTIVITY OF ETHANOLIC EXTRACT OF SEEDPOD AND QUERCETIN OF NELUMBO NUCIFERA GAERTN
Journal Title: Asian Journal of Pharamceutical and Clinical Research - Year 2019, Vol 12, Issue 1
Abstract
Objective: The objective of the study was to evaluate whether ethanolic extracts of Nelumbo nucifera (EENN) seedpod and quercetin (active component of NN) possess antibacterial proprieties against Gram (-) bacteria such as Escherichia coli and Pseudomonas aeruginosa and Gram (+) bacteria such as Staphylococcus aureus. Methods: Antibacterial activities of EENN seedpod and quercetin were investigated using disc diffusion method, minimum inhibitory concentration against E. coli and P. aeruginosa and Gram (+) bacteria such as S. aureus. Results: The antibacterial activity of both EENN seedpod and quercetin was found to be increased in dose-dependent manner. The maximum zone of inhibition was exhibited by both EENN seedpod and quercetin against E. coli (14 mm and 15 mm) and P. aeruginosa (13 mm and 15 mm). Gram-negative bacteria were more susceptible to the EENN seedpod extract and quercetin than Gram-positive bacteria.Conclusion: The results of the present study suggested that the effect of EENN seedpod and quercetin against the tested bacteria in vitro may contribute to the in vivo activities of the EENN seedpod and quercetin.
