GRAPHICAL ABSTRACT
ABSTRACT
Origanum majorana L., (OM), O. onites L. (OO) and O. syriacum L. (subsp. bevanii (Holmes) Greuter & Burdet) (OS) are belong to Majorana (Mill.) Benth. section of Origanum L. genus. In this study, quantities of some phenolic compounds; gallic acid, syringic acid, p-hydory benzoic acid, caffeic acid, (E)-ferulic acid, chlorogenic acid, rosmarinic acid, pyrogallol and vanillin; in the chloroform (C), acetone (Ac) and methanol (M) extracts prepared from Origanum species collected from Türkiye were investigated via liquid chromatography and tandem mass spectrometry (LC-MS/MS). The relative standard deviations (RSD) of the phenolics were found as follows; 4.85, 8.39, 4.78, 8.04, 5.21, 5.45, 3.73, 5.47, respectively. Curcumin was used as an internal standard (RSD was 6.57). In the extracts, (E)-ferulic acid and caffeic acid found to be the most abundant compounds. OS was determined as the richest species in terms of phenolic acids. For the investigated analytes, the correlation coefficient was found in the range of 0.9803 to 0.9982.
