The composition of Taif rose oil

Abstract

Fresh flowers of Rosa damascena Miller var. trigintipetala Dieck cultivated in Taif, Saudi Arabia, are the source of Taif rose oil. Two oil samples were sourced from two dealers in Riyadh, Saudi Arabia, in 2011. They were analyzed by gas chromatography (GC) and GC/mass spectrometry (GC/MS). Both oils gave a similar profile with quantitative differences. The main components characterized were citronellol (23-28%), geraniol (14-20%), nonadecane (11-16%), nerol (6-11%), linalool (8%) and heneicosane (7%).
