Abstract Matricaria sevanensis is a widespread plant species grown in Central Anatolian and helps to prevent sleep disorders, influenza and stomach upsets when consumed in tea form. In this study, the essential oil from aerial parts of M. sevanensis collected from Osmaniye Province of Turkey was obtained by solvent-free microwave-assisted distillation at 340 W in 30 min and its chemical compounds, some thermal characteristics, functional groups and antioxidant activity were investigated by gas chromatography/mass spectrometry (GC/MS), differential scanning calorimetry (DSC), Fouriertransform infrared (FTIR) spectroscopy and 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging assay, respectively. Also, temperature values were recorded in every 5 min of distillation process in order to visualize a profile depending on time. Oil yield was nearly 0.04% (v/w), and eighteen components were totally identified by GC/MS. Bisabolene oxide A (50.32%), (Z)-b-farnesene (24.20%), a-bisabolol oxide A (8.12%) and a-farnesene (4.06%) were found as major compounds. Three peaks were observed in DSC graph, and onset temperatures (To), peak temperatures (Tp) and enthalpy (DH) values were specified. FTIR spectra showed that several functional groups such as alcohols, alkanes, aromatics, amines and ethers were present in essential oil. Antioxidant activity (IC50) of M. sevanensis essential oil was also computed as 156.005 lg mL-1 (p \ 0.05). Keywords Matricaria sevanensis Essential oil GC/MS Thermal analysis Antioxidant activity
Introduction Genus Matricaria which belongs to the family Asteraceae has 22 taxa in the world, and also, 5 taxa (M. aurea, M. chamomilla var. chamomilla, M. chamomilla var. pappulosa, M. recutita and M. sevanensis) are grown in Turkey [1–3]. This genus is very similar to the genus Tripleurospermum morphologically [4]. These genera are widespread in Asia, Africa, North America and Europe [5]. Related plants consumed as chamomile tea and used in alternative medicine for people suffering from sleep disorders [6]. Essential or ethereal oils which are comprised of volatiles from plant materials are used as alternatives for ¨ zge Su¨fer & O [email protected] 1

synthetic compounds in various industries like cosmetics and food [7]. The characterization of essential oil from both the genera Matricaria and Tripleurospermum by gas chromatography/mass spectrometry (GC/MS) has been reported in the literature by several researchers [8–12]. Many of them were focused on the essential oil components of Matricaria and Tripleurospermum and reported major compounds at the rates of 3
