Abstract
In this research, essential oils were extracted by hydro-distillation method but with different apparatus of distillation from Rosa damascena Mill. The oil obtained at different yields for example for Clevenger (0.008%), Miquel (0.014%), A.O.A.C. (0.012%) and two plans designed in Research Institute of Forests and Rangelands by authors which were named plan-1 (0.015%) and plan-2 (0.023%). Samples were analyzed by GC and GC/MS. The main constituents of the oil by Clevenger were geraniol (26.7%), n-nonadecane (21.3%), citronellol (12.5%) and n-henicosane (12.0%); by Miquel were geraniol (32.9%), citronellol (19.0%), n-nonadecane (10.6%); by A.O.A.C. were n-nonadecane (28.5%), geraniol (22.6%), n-henicosane (10.6%) and citronellol (10.2%) in plan -1 were n-nonadecane (21.3%), geraniol( 21.8%), citronellol (12%) and in plan-2 were n-nonadecane (21.8%), geraniol (19.1%) and citronellol (15%), respectively. By comparison of the results from different apparatus of hydro-distillation, it can be concluded that the best plan for obtaining essential oil from Rosa damascena Mill., were plan-2 and Miquel.
