Abstract

Article history: In this research, extraction of an essential oil from Cleome coluteoides Boiss aerial parts was investi- Received 19 December 2015 gated using supercritical carbon dioxide (SC-CO ) technique for the first time. Design of experiments and Received in revised form 11 April 2016 process optimization was carried out with response surface methodology (RSM) based on the central Accepted 12 April 2016 composite design (CCD). Influence of operating parameters including pressure (P = 100–220 bar), tem- Available online 22 April 2016 perature (T = 308–328 K), particle size (d = 0.3–0.9 mm) and dynamic extraction time (t = 30–150 min) on final response was evaluated. The experimental values were adequately fitted to a quadratic polynomial Keywords: equation. Analysis of variance (ANOVA) results indicated that all factors were significantly affected the Cleome coluteoides Boiss extraction yield of essential oil from C. coluteoides. Using a grey wolf optimization (GWO) algorithm, the Supercritical CO extraction optimal operating conditions were determined to be P = 220 bar, T = 308 K, d = 0.58 mm and t = 135 min, Response surface methodology under which conditions, the maximum yield of 0.6589 was obtained.
