| Rose, Rosa centifolia, ext. Usage And Synthesis |
| Chemical Properties | Rose grows as a plant, shrub, bush or thicket. The flowers exhibit a five-petal calyx and a multiple five-petal corolla. Like the corolla, the seeds are inserted in the calyx. The plant is of Asiatic origin. Countries where rose is extensively cultivated for extractive purposes include Bulgaria, Turkey, Morocco, France and Italy. The parts used are the flowers, buds, leaves and fruit (hips). Rose has a deep, warm, rich rose odor with a slightly bitter, sharp flavor at high concentrations; pleasant on dilution. The fragrance of the rose flower, captured by extraction, is one of the most valuable flavor and fragrance products used. The most common aroma concentrates of rose are rose oil and rose water, derived from steam distillation; and rose concrete and rose absolute from solvent extraction. Of these, rose oil and rose concrete are produced in the largest quantities.The choice of rose derivatives for flavor application is often determined by the feasibility of introducing water-soluble β-phenethyl
alcohol into the flavor complex. This component is present in large quantities in the extracts; it is almost absent in distillates and may,
therefore, have a significant effect on the resulting aroma | | Occurrence | Found in the flowers of Rosa centifolia L. (Fam. Rosaceae) (Guenther, 1952; Naves, 1974). | | Preparation | By extraction with volatile solvents, which are subsequently removed, usually under vacpum, followed by redisolution in alcohol, chilling, filtration and removal of the alcohol. |
