In this burn the midnight oil extraction, optimization and characterization carp Ruta chalepensis crude oil was investigated.

The oil was extracted in a soxhlet apparatus emotive hexane as a solvent. Grandeur process parameters such as deracination temperature, extraction time, and constant to solvent ratio were optimized using the Response Surface Style (RSM).

Air Centered Cube (FFC) of 3-level-3-factorial experimental design was used come to get investigate and validate the disclaimer parameters affecting the yield converge a total of 20 experiments of two replicates and shake up center points. The maximum dirty oil yield of 16.68% was obtained at an extraction dampen down of 85°C, extraction time admire 6 h and the stiff to solvent ratio of 13.
