title: [Optimization for supercritical CO2 extraction with response surface methodology and component analysis of Sapindus mukorossi oil].
abstract: OBJECTIVE
  To study the extraction conditions of Sapindus mukorossi oil by Supercritical CO2 Extraction and identify its components.
  
  
  METHODS
  Optimized SFE-CO2 Extraction by response surface methodology and used GC-MS to analysie Sapindus mukorossi oil compounds.
  
  
  RESULTS
  Established the model of an equation for the extraction rate of Sapindus mukorossi oil by Supercritical CO2 Extraction, and the optimal parameters for the Supercritical CO2 Extraction determined by the equation were: the extraction pressure was 30 MPa, temperature was 40 degrees C; The separation I pressure was 14 MPa, temperature was 45 degrees C; The separation II pressure was 6 MPa, temperature was 40 degrees C; The extraction time was 60 min and the extraction rate of Sapindus mukorossi oil of 17.58%. 22 main compounds of Sapindus mukorossi oil extracted by supercritical CO2 were identified by GC-MS, unsaturated fatty acids were 86.59%.
  
  
  CONCLUSIONS
  This process is reliable, safe and with simple operation, and can be used for the extraction of Sapindus mukorossi oil.
