Abstract
Screening the content of fragrance allergens (citral, geraniol, trans-cinnamaldehyde, hydroxycitronellal, cinnamyl alcohol, eugenol, dihydrocoumarin, methyl eugenol, iso-eugenol, coumarin, eugeyl acetate, α-hexylcinnamadehyde) in commercial essential oils and containing essential oil drugs has been using a gas chromatographic method. We selected 7 essential oils based on eugenol Derivatives for more content and can be used to process photo-irradiation. Comparision with results of photochemical product obtained from essential oils shows good agreement with standard eugenol derivatives using GC determination. The fragrances stability, antioxidation effectiveness and possible photochemical reaction products were investigated by LC-UV and LC-MS methods.
