Description

The aim of this study was to investigate potential antimicrobial activity of phytochemical extracts of commercially available species of Plantago. Plantago is a medically relevant genus, with several species traditionally used worldwide to treat inflammation and various infections. Dried leaf material of both species was extracted using a Soxhlet apparatus. Nonpolar (hexane) extracts were obtained from both P. subnuda and P. eriopoda, as well as a polar (methanol) extract from P. eriopoda. Minimum inhibitory concentration (MIC) assays were performed using 96-well microtiter plates against seven different bacterial species (Escherichia coli, Bacillus megaterium, Klebsiella pneumoniae, Mycobacterium smegmatis, Pseudomonas aeruginosa, Serratia marcescens, and Staphylococcus aureus). Final results were obtained only from the nonpolar (hexane) and polar (methanol) extracts from P. eriopoda. No tests using either P. eriopoda extract showed bacterial inhibition. However, tests using the methanol extract have yet to be completed for four bacterial species. Further review of the literature using P. major suggests that concentrations used may have been insufficient to exhibit antimicrobial activity. Future studies are planned using extracts from two other Plantago species, starting at higher maximum concentrations.
