Antimicrobial and Antioxidant Activities of Some Mosses

Abstract

This study investigated the in vitro antimicrobial and antioxidant activity of six mosses: Plagiomnium medium (Bruch & Schimp.) T.J.Kop, Leptodon smithii (Hedw.) F.Weber & D.Mohr, Rhynchostegium alopecuroides (Brid.) A.J.E.Sm., Nogopterium gracile (Hedw.) Crosby & W.R.Buck, Pylasia polyantha (Hedw.) and Timmia bavarica (Hessl.). The antimicrobial activity of prepared moss ethanol extracts was determined using the disk diffusion method against 20 strains. In addition, the antioxidant activities to determine for studied mosses 2,2-diphenyl-1-picrylhydrazyl (DPPH) antioxidant capacity determination method was used As a result of the antimicrobial activity test, all moss samples, except Rhynchostegium alopecuroides (Brid.) A.J.E. Sm, were effective on multi-drug resistant and standard Staphylococcus aureus strains, which is an important nosocomial infection. As a result of the antioxidant activity test, an antioxidant effect was observed in all samples, and it was determined that the P. medium sample had the highest effect with an EC50 value of 6.0826 μg/mL.
