TOTAL PHENOLIC CONTENT, ANTIOXIDANT AND ANTIBACTERIAL ACTIVITIES OF THE EXTRACT OF EPHEDRA PROCERA FISCH. ET MEY.

Abstract

Ephedra prcera belonging to the family Ephedraceae is a poison and medicinal plant. The main aim of present study was to determine total phenolic content and antioxidant and antibacterial activities of ethanolic extract from the aerial parts of E. procera collected from a natural habitat in Chaharmahal va Bakhtiari province, Southwestern Iran. The total phenolic content of the extract by Folin-Ciocalteu method and the antioxidant activity using DPPH assay were determined. The antibacterial activity, minimum inhibitory concentration (MIC), and minimum bactericidal concentration (MBC) of the extract were evaluated against five bacteria, including Proteus vulgaris, Pseudomonas aeruginosa, Enteobacter aeogenes, Bacillus ceirus and Staphylococcus aureus. Total phenolic content in the extract of E. procera was 0.718 mg tannic acid/g dry weight extract. The results indicated that the ethanolic extract of E. piocera exhibited radical scavenging activity. In addition, the results of this study confirmed that the ethanolic extract of E. procera exhibited antibacterial activity. In conclusion, the extract of E. piocera could be an important source of phenolic components with antioxidant capacity and antibacterial activity.
