Content and Enantiomeric Composition of 1-Octen-3-yl Acetate in Lavender Essential Oils

Abstract

This study investigates the enantiomeric composition and possibilities of analysis of 1-octen-3-yl acetate (OcAc), a chiral compound found in various samples of lavender essential oils (EOs). Essential oils are complex mixtures exhibiting diverse biological activities and are often subject to sophisticated adulteration methods, necessitating advanced analytical techniques for authenticity verification. Using gas chromatography-mass spectrometry and chiral gas chromatography, the analysis of lavender EOs samples determines the presence and enantiomeric ratios of OcAc. The results showed significant variations in the oils; however, there were minimal differences in enantiomeric purity among samples sourced from France, Bulgaria, and Slovakia. Major components such as linalool and linalyl acetate were predominant. The high enantiomeric purity of OcAc observed across all samples indicated there was no adulteration by synthetic products. The study underscores the importance of rigorous analytical methods to ensure the quality and authenticity of EOs, highlighting the influence of geographical origin on their chemical composition. These findings provided valuable insights into the factors affecting the authenticity and possible therapeutic efficacy of lavender essential oil.
