Determination of Antioxidant Activities of Essential Oils of Crataegus orientalis var. orientalis in Tokat (Türkiye) Province

Abstract

Medicinal plants are quite popular in the medicine development process because they contain bioactive chemicals. Traditional medicine has made extensive use of Crataegus orientalis L., which also has significant biological effects. In this study, essential oils (EOs) of C. orientalis var. orientalis collected from Tokat-Türkiye were isolated by hydrodistillation. Chemical constituents were detected by GC-MS and benzaldehyde (%52.75), α-terpineol (%16.86), germacrene D (%7.03) and caryophyllene (%6.77) were determined as major components. Moreover, antioxidant analyses including DPPH•, ABTS+• and FRAP tests were carried out. EOs displayed good the DPPH activity (IC50, 12.21, µg/mL) in comparison to the standard BHT (IC50, 10.23 µg/mL). The same trend was observed for ABTS and FRAP assays.
