Title: Study on CO_2 Supercritical Fluid Extraction of Volatile oil in Radix Angelica Sinensis, Rhizoma Chuanxiong and Rhizoma Cyperi through Homogeneous Design and β-Cyclodextrin Inclusion Compound
Abstract: Objective To explore the preparation technology of CO 2 supercritical fluid extraction of compound volatile oil and β-cyclodextrin inclusion compound for the volatile oil.Method Orthogonal test and homogeneous design were used.Result The best inclusion condition was inclusion pressure 30 Pa,inclusion temperature 60 ℃, separation temperatureⅠ60 ℃,separation temperatureⅡ30 ℃ and inclusion time 4.0 h. The best preparation technological condition of β-CD inclusion compound was the proportion of water and oil to β-cyclodextrin 1∶10(mL),the mode of grinding, time 60 min.Conclusion The best inclusion technology and β-cyclodextrin inclusion compound of volatile oil are confirmed.
