Antibacterial and antioxidant activity of Juniperus thurifera L. leaf extracts growing in East of Algeria

Article scientifique 2018 Anglais

Résumé

AIM: L., which is an Algerian endemic tree that belongs to the family of Cupressaceae. MATERIALS AND METHODS: The plant leaves were extracted in solvents of increasing polarity to obtain different extracts such as methanol, petroleum ether, chloroform, ethyl acetate, and aqueous extracts (MeE, PEE, ChlE, EtAE, and AqE). The antioxidant activity of four extracts (MeE, ChlE, EtAE, and AqE) was assessed by trapping test of 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical. The evaluation of antibacterial activity of MeE, ChlE, EtAE, and PEE was done using the disk diffusion method on solid agar. RESULTS: (extended spectrum β-lactamase). CONCLUSION: L. leaves extracts exhibited a very intense antioxidant potential toward the DPPH radical, and on the other hand, the antibacterial activity showed an action spectrum exclusively toward the Gram-positive bacteria.
