Abstract :
Citrullus Colocynthis is a herbal plant with rich content of phytochemicals. This old plant in Iran have been used for Diabetic disease. This research, the supercritical fluid extraction (SFE) with carbon dioxide (CO2) and Ethanol (Etoh) as co-solvent was applied to obtain the yield and the combination of components. Then Citrullus Colocynthis,s essential oil was analyzed by GC-MS tests. The extraction was explored at various operating condition using 150,170,190 bar and 35, 40, 45 Ëšc. With comparison of all of these operation condition results, the best operation condition was obtained in 190 bar and 45 Ëšc. The yield in this situation was 26.576. and the constituents were identified and divided into five classes include: alcohols ,alkanes, hydrocarbons, esters and acids.1,2-benzenedicarboxylicacid, mono(2-ethylhexyl)ester,4-Benzenedicarboxylic acid, bis(2-ethylhexyl) ester , Phthalic acid, 6-ethyloct-3-yl 2-ethylhexyl ester , and n-hexadecanoic acid.
