Özet

Four species of bryophytes were used as material and were gathered from various areas in Mount Ida (Kazdag), Canakkale, Turkey. Volatile compounds were isolated from the moss species with solid phase microextraction (SPME). GC-MS was applied to determine volatiles. The antioxidant capacity of bryophytes was established using CERAC and CUPRAC techniques. Trolox equivalent (TEAC) of aqueous extract of bryophytes was determined at concentrations of 0.0109 (+/- 0.0008)-0.0212 (+/- 0.0009) mmol trolox/g bryophyte and 70% methyl alcohol extract 0.0259 (+/- 0.0013)-0.0058 (+/- 0.0012) mmol trolox/g bryophyte using the CERAC technique and for water extract as 0.0027 (+/- 0.0006)-0.0083 (+/- 0.0012) mmol trolox/g bryophyte and methanol extract 0.0035-0.0095 (+/- 0.0005) mmol trolox/g bryophyte using the CUPRAC technique. The total flavonoid content was analyzed as equivalent mmol catechin/g bryophyte with the AlCl3/NaNO2 colorimetry technique. The total phenolic content of the species was analyzed with a Folin-Ciocalteu spectrophotometric technique.
