Rosa × centifolia - Rosaceae
provence rose, rose de Mai, cabbage rose, Provence-Rose, Zentifolie, Kohl-Rose

Old hybrid rose developed by Dutch rose breeders in 16th and 17th century; flowers globular, petals numerous, pink, white or dark red, highly scented; cultivated in Egypt, France (Provence: Grass) and Morocco.

R.centifolia flower absolute (CAS 84604-12-6) is made from concrete oil (petrol ether extract of the rose petals) by dissolving in a minimum volume of absolute alcohol to remove the natural waxes and then distill the alcohol off (and finally bubbling nitrogen gas through the residue).
„Rosa centifolia showed 0.225% concrete oil and 0.128% yield of absolute oil… High-resolution gas liquid chromatographic (HR-GLC) analysis of the essential oil of R. centifolia, showed the phenethyl alcohol, geranyl acetate, geraniol and linalool as major components whereas, benzyl alcohol, benzaldehyde and citronellyl acetate were detected at trace levels.“
