The aim of this study were to determine total phenol contents, antibacterial and antioxidant activity of bryophyte species including Plasteurhynchium striatum (Spruce) M. Fleisch, Palamocladium euchloron (Bruch ex Müll. Hal.) Wijk & Margad. and Cratoneuron filicinum (Hedw.) Spruce and Campyliadelphus chrysophylus (Brid.) R.S. Chopra. Antibacterial activity of methanolic, ethanolic, chloroform, acetone and water extracts of these species was determined by microdilution method. Antioxidant activity of these species was evaluated by 2,2-diphenyl-1-picrylhydrazyl free radical-scavenging ability. The total phenol content of these species was determined quantitatively using the folin ciocalteu reagent, with gallic acid equivalents as the standard. The highest DPPH free radical scavenging activity was observed in about 65% C. filicinum. Total phenolic content of P. euchloron was determined the highest extract value of 0,027±0,002 mg/g. The methanol extract of bryophytes was found to have significant antioxidant activity and phenolic contents. Antibacterial effect of the extracts was not observed against the tested microorganisms
