Phytochemical Analysis and Antibacterial Activity of Berberis vulgaris Extract

Background: Plants are main source of various bioactive compounds that possess great medicinal importance and have gained much popularity for therapeutics due to their less side effects. A diverse category of plants is present to be explored and evaluated for the treatment of different bacterial infection. In the current work, Berberis vulgaris extract in various solvents was evaluated for its phytochemical properties and antimicrobial potential against six different pathogenic bacterial strains.Methods: Different phytochemical tests were carried out to analyze the plant for active biocomponents. The disc diffusion method was used to screen the plant for different pathogenic bacterial strains. Phytochemical analysis revealed the presence of various plant bioactive compounds (alkaloids, saponins, tannins, flavonoids, terpenoids, carbohydrates, and proteins) in variable amount.Results: Among all solvents extracts, butanoic and aqueous fraction showed abundant presence of bioactive compounds, while n-hexane showed least intensity of various phytochemicals. For antimicrobial potential, methanolic and butanoic fractions showed maximum growth inhibition against all strains tested at 1.5mg disc-1. Ethyl acetate and n-hexane also showed better activity against all tested bacteria at all concentrations. The most susceptible microbe was Bacillus subtilis. These results further revealed that least activity was recorded by water extracted solvent and showed no activity against Staphylococcus aureus at all concentrations.Conclusion: The current work highlights the apparent antimicrobial potential of extract derived from of Berberis vulgaris. This plant may be explored for further activities and can be used for the production of antibiotics.
