Phytochemical characterization and antibacterial activity of Eclipta alba (L.) L. (Asteraceae) against some dental micro flora from Mewar region of Rajasthan, India

Abstract

In the current study, phytochemical characterization and antibacterial activi-ty of Eclipta alba (L.) L. leaf extract against some dental micro flora have been investigated. Plant species was collected from Chittorgarh district Mewar region of Rajasthan. Dried leaves were subjected to methanol extrac-tion. Phytochemical investigation was carried out to determine the possible bioactive components in the methanol extract of E. alba leaves using standard methods. All concentrations of the extract exhibited considerable antibacterial activity against Escherichia coli, Pseudomonas aeruginosa, Bacillus subtilis and Micrococcus luteus. During the study 100 mg/ml extract showed maximum zone of inhibition 13 mm against E. coli, 12 mm against P. aeruginosa and 14 mm zone of inhibition against B. subtilis, 12 mm zone of inhibition against M. luteus.
