Abstract :The antimicrobial and antioxidant activities of the acetone extracts of lichen Pseudevernia furfuracea var. furfuracea insert ignore into journalissuearticles values(PF); and Evernia prunastri insert ignore into journalissuearticles values(EP); were investigated. Different antioxidant tests were applied such as ABTS insert ignore into journalissuearticles values(2,2`-azino-bis insert ignore into journalissuearticles values(3-ethylbenzthiazoline-6-sulfonic acid); radical scavenging activity and reducing power. Antimicrobial activities of lichen extracts were determined by agar well diffusion method and micro-well dilution assay. All lichen extracts exhibited antimicrobial activity against test bacteria. Antioxidant activity of PF extract is higher than EP extract. Acetone extracts of PF and EP could be considered as a source of natural antioxidant and antimicrobial agent.
