Abstract:
Taking Zizyphi spinosi Semen as material,supercritical CO2 fluid extraction of the fatty oil from Zizyphi spinosi Semen was carried out,the extraction temperature,pressure,time and the sample particle size were independent determined and the conditions were evaluated by response surface methodology(RSM).The results showed that the maximum extraction yield of about 20% was achieved at extract temperature of 40 ℃,pressure of 395 bar,dynamic extraction time of 2.5 h and power particle size of 40 mesh.The chemical compositions of fatty oil were investigated by GC-MS.The results indicated that supercritical CO2 fluid extraction method was the suitable method,the main fatty acids were 10-octadecenoic acid,octadecanoic acid,9,12-octadecadienoic acid and palmitic acid,respectively.Supercritical fluid extraction was proved to an effective technique for extracting fatty oil from Zizyphi spinosi Semen.
