Rose oil Rose oil Rose oil (rose otto, attar of rose, attar of roses or rose essence) is the essential oil extracted from the petals of various types of rose. "Rose ottos" are extracted through steam distillation, while "rose absolutes" are obtained through solvent extraction, the absolute being used more commonly in perfumery. Even with their high price and the advent of organic synthesis, rose oils are still perhaps the most widely used essential oil in perfumery. Two major species of rose are cultivated for the production of rose oil: The most common chemical compounds present in rose oil are: The key
Bergamot essential oil process and allows for the detection of possible adulteration. The combined use of isotope ratio mass spectrometry and SNIF-NMR (Site-Specific Natural Isotope Fractionation-Nuclear Magnetic Resonance) allows discovering adulteration otherwise undetectable even allowing for the identification of the geographical origin of the essential oil. The GC-C-IRMS (Gas Chromatography-Combustion – Isotope Ratio Mass Spectrometer) technique, the most recently used, allows obtaining similar results. Analytical values take as reference for genuinity evaluation of bergamot essential oil by the "Experimental Station for the Industry of the Essential oils and Citrus products", in Reggio Calabria, Italy. The phototoxic effects of bergamot essential oil have been
