Method Development for Analysis of Essential Oils Authenticity using Gas Chromatography-Mass Spectrometry (GC-MS)

Essential oils widely used as fragrances and flavours in the food and cosmetics industry and also for the medical and pharmaceutical fields for various effects. The demand increasing of essential oil caused the cases of adulteration that affect the authenticity of essential oil. The authenticity is important in ensuring the quality of essential oil. This study was aimed to analyse the authenticity of essential oil use Gas ChromatographyMass Spectrometry (GC-MS) by determining its chemical component. The experiment included repeatability, accuracy, and limit of detection. GC performed on HP-5MS capillary column operated in 600C-2400C temperature programs. This method successfully applied to all types of essential oil with limit detection of clove oil was 0.02 ppm, citronella oil was 0.033 ppm, patchouli oil was 0.005 ppm, and lemongrass was 0.016 ppm. All types of essential oil also have good repeatability and accuracy with these methods. This study will facilitate the scientific community by enhancing the efficient method for essential oil.
