Federica Pellati (1), Giulia Orlandini (1), Katryna A. van Leeuwen (2), Giulia Anesin (1,2), Davide Bertelli (1), Mauro Paolini (2), Stefania Benvenuti (1) and Federica Camin (2) The essential oil of Rosa damascena Mill. is known for its fine perfumery application, use in cosmetic preparations and for several pharmacological activities. Due to its high value, it can be easily adulterated with flavors or cheaper oils. This study is aimed at a detailed phytochemical characterization of commercial samples of R. damascena essential oil and at their authenticity assessment. Nineteen commercial samples of R. damascena essential oil of different geographic origin and an additional authentic one, directly extracted by hydro-distillation from fresh flowers, were considered. GC/MS and GC/FID techniques were applied for the phytochemical analysis of the samples. EA/IRMS (Elemental Analyzer/Isotope RatioMass Spectrometry) and GC/C (Combustion)/IRMS were used to determine the d13C composition of bulk samples and of some specific components.
