Phenolic compounds from section Majorana (Mill.) Benth of Origanum L. species extracts via validated LC-MS/MS method

Abstract

AbstrAbstract: 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. In the extracts, ( E )-ferulic acid and caffeic acid were found to be the most abundant compounds. O. syriacum was determined as the richest species in terms of phenolic acids.
