Supercritical Extraction of Citrullus Colocynthis Plant Using Carbon Dioxide

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 691,671,651 bar and 59, 01, 09 ˚c. With comparison of all of these operation condition results, the best operation condition was obtained in 651 bar and 09 ˚c. The yield in this situation was 21.971. and the constituents were identified and divided into five classes include: alcohols ,alkanes, hydrocarbons, esters and acids.6,2-benzenedicarboxylicacid, mono(2-ethylhexyl)ester,0-Benzenedicarboxylic acid, bis(2-ethylhexyl) ester , Phthalic acid, 1-ethyloct-5-yl 2-ethylhexyl ester , and n-hexadecanoic acid
