Lavender essential oil (LEO) is widely utilized in aromatherapy, cosmetics, pharmaceuticals, and the food industry due to its biological properties and appealing fragrances. This study examines the influence of two concentrations (5% and 10%) of NaCl and KCl on the chemical composition of LEO. Hydrodistillation was conducted with a 1:10 hydromodule ratio using a Clevenger-type apparatus for 120 minutes. Gas chromatography-mass spectrometry (GC-MS) was employed to analyze the chemical composition of LEO. A total of 54 compounds were identified, with linalool (26.2-27.1%), linalyl acetate (16.4-18.1%), and lavandulyl acetate (5.9-6.4%) being the predominant compounds. Regardless of the added salts and their concentrations, no significant impact on the quality and composition of LEO was observed. However, comparative analysis revealed a slight increase in 1-octen-3-yl acetate and myrtenal, while linalool, linalyl acetate, 1,8-cineole, (E)-caryophyllene, (Z)-β-ocimene, and (E)-β-ocimene were reduced by up to 5% in the oils obtained with the salt presence. Although salts are known to enhance the recovery of certain volatile constituents, the magnitude of this effect varies depending on the type and concentration of the salt applied. Therefore, further research in this field is necessary to explore alternative lavender pretreatment methods and identify more efficient extraction techniques.
