A Study on Antioxidant and Antimicrobial Activity of Ferulago galbanifera Species

Abstract

In this work, antimicrobial effects of the root, stem, leaf and flower parts extracts with ethanol and acetone of Ferulago galbanifera species against Escherichia coli, Staphylococcus epidermidis, Enterococcus faecalis Candida albicans, Bacillus subtilis, Pseudomonas aeruginosa, Staphylococcus aureus, Salmonella typhimurium strains were investigated by using the disc diffusion method. In addition to that, antioxidant activity of F. galbanifera ethanolic extracts was measured using the DPPH method, as well as their total phenolic content using the Folin-Ciocalteu’s phenol reagent technique. To our results, ethanolic extracts of leaf from F. galbanifera were found to have antimicrobial effect against the all microorganisms, whereas the acetonic extracts of leaf has shown antimicrobial effects to some microorganisms other than Staphylococcus epidermidis, E. faecalis, C. albicans species. Extracts obtained from the root and the flower parts of the plant had no antimicrobial effect on the test microorganisms. The antioxidant activity level was found to be in the following order (from the highest to the lowest): flower, leaf, stem and rood; 16.32, 215, 244, 323(μg/mL), respectively. The highest total phenolic content obtained from the parts of the plant F. galbanifere was for the root, while the lowest was for its leaf part.
