In view of the fact that there are lots of diverse sources of medicinal plants in our country, development of related technologies can be given special priority. In this study, one of the newest developed technologies for the extraction of active components of plant, gas - solvent process by using of hydro fluorocarbons, was introduced. A set up for this extraction method was designed and manufactured in Iranian Research Organization for Science and Technology (IROST) for the first time in Iran and it was applied for the extraction of essential oil from the bark of cinnamon and cumin seeds. For this purpose, HFC-R134a‌ was chosen as the solvent and operation conditions were changed in the term of pressure, particle size and time of extraction according to Taguchi experimental design method. Cinnam aldehyde for cinnamon and cumin aldehyde, g-Terpinen-7-al and α-Terpinen-7-al for cumin were considered as indicator and their obtained amount from this extraction method was compared with the traditional hydro distillation method. Optimum extraction condition for both of cinnamon bark and cumin seeds were obtained as: 10 bar, mean particle size of 0.3 mm and time of 120min. In comparison with the hydro distillation, amount of extracted active components at optimum condition showed a 13% and 12% increase for cinnamon and cumin, respectively which indicates an improvement in the quality of extracted essential oil from gas – solvent method by R134a relative to the hydro distillation.
