Roses are always appreciated because of their inimitable aroma, many uses and  of course their beauty. In addition to the different damask rose (Rosa  damascena Mill.) products (oil, water, concrete, absolute, gulkand etc.), its  dried petals are also used for various health purposes. The hydrodistilled  volatile oil and water of shade-dried damask rose petals were investigated by  GC and GC-MS. The predominant components of tThe essential oil and rose water  were aliphatic hydrocarbons (56.4 and 46.3%), followed by oxygenated  monoterpenes (14.7 and 8.7%). The main aliphatic hydrocarbons of the  essential oil and rose water were heneicosane (19.7 and 15.7%), nonadecane  (13.0 and 8.4%), tricosane (11.3 and 9.3%) and pentacosane (5.3 and 5.1%)  while the content of 2-phenyl ethyl alcohol was 0.4% and 7.1% in the  essential oil and rose water, respectively. The chemical composition of the  dried rose petal volatiles is quite different from fresh flower volatiles
