 Rosa centifolia petals produced 0.225% concrete oil and 0.128% absolute oil. Analysis of the essential oil of R. centifolia showed phenylethanol (43.0%), geranyl acetate (15.6%), geraniol (10.5%) and linalool (6.9%) as major components. Benzyl alcohol (3.3%), benzaldehyde (1.5%) and citronellyl acetate (0.3%) were minor constituents beside unidentified compounds. \\ Rosa centifolia petals produced 0.225% concrete oil and 0.128% absolute oil.

 +Application of GC-­HRMS to rose absolutes of R.centifolia and R.damascena confirmed the identification of 19 new esters like the linoleates and linolenates of phenylethanol, citronellol, nerol and geraniol. "With these identified esters, the known volatile fraction of rose absolute increased from 90 percent to 92." \\
