Abstract

In this study extraction, optimization and characterization of Ruta chalepensis crude oil was investigated. The oil was extracted in a soxhlet apparatus using hexane as a solvent. The process parameters such as extraction temperature, extraction time, and solid to solvent ratio were optimized using the Response Surface Methodology (RSM). Face Centered Cube (FFC) of 3-level-3-factorial experimental design was used to investigate and validate the extraction parameters affecting the yield with a total of 20 experiments of two replicates and six center points. The maximum crude oil yield of 16.68% was obtained at an extraction temperature of 85°C, extraction time of 6 h and the solid to solvent ratio of 13.
