Antimicrobial and antioxidant activities and volatile constituents of Eurhynchium angustirete (Broth.) T. J. Kop. and Isothecium alopecuroides (Lam. ex Dubois) Isov. from Turkey

The aim of the present study was to determine chemical analysis, antimicrobial and antioxidant effects Eurhynchium angustirete (Broth.) Isothecium alopecuroides (Lam. Ex Dubois) essential oil obtained by distillation method (Clevenger apparatus hydrodistillation). Obtained volatile oils were identified gas chromatography-mass spectrometry (GC/MS) which revealed presence twenty-two components analyzed in E. representing 95.7% total compounds twenty determined I. 94.3% compounds. Trans-pinocarveol myrtenal as major constituents 23.0% 14.1% main were: biformene (9.9%), ?-pinene (9.1%), bornyl acetate (8.4%) alopecuroides. from showed higher metal-ion chelating activities 65.93±0.39% 31.01±2.75, respectively. There no significant difference results DPPH activity 16.8±6.98 22.8%±8.91, investigated microdiution method. isolated effective against Escherichia coli ATCC25922, Enterococcus faecalis ATCC29212, Staphylococcus aureus ATCC25923, Pseudomonas aeruginosa ATCC2785 Streptococcus mutans. Antimicrobial effect values found ranging 90.76-95.38%. According value microorganism, than
