Abstract
Background: Pharmaceutical world is currently facing a major issue of bacterial resistance against antibiotics. For the past few years, plants being an excellent source of phytochemicals have replaced many traditional antibacterial agents. Keeping this in view, the current study was conducted to detect the antibacterial activity and the presence of various phytochemicals in Convolvulus arvensis leaves and stem extracts.
Methods: Eight different organic and aqueous extracts of Convolvulus arvensis L. (C. arvensis) leaves and stem were prepared and their antimicrobial activity against 13 clinically important bacterial species was investigated using the disc diffusion assay. Phytochemical screening of the aqueous extracts of C. arvensis was performed using qualitative tests.
Results: All the thirteen bacterial species tested in this study were found sensitive to the stem and leaf extracts of C. arvensis. Highest antimicrobial activity was observed against Escherichia coli while among all the extracts butanol extract was the most effective antimicrobial agent. Phytochemical analyses using organic and aqueous extracts confirmed the presence of various secondary plant metabolites of therapeutic value i.e. saponins, flavonoids, steroids, tannins, phlobatannins, cardiac glycosides and coumarins.
Conclusion: Our results indicate that C. arvensis plant contains some phytochemicals with antimicrobial affects. These chemicals possess great potential to be used as advanced therapeutic compounds against broad range of pathogenic bacteria.
