摘要
采用超临界CO2萃取法(SCDE)萃取来自四地的五味子,探讨其木质素含量的区域性差异。超临界CO2萃取提取工艺条件为:萃取釜压力18MPa,萃取温度40℃,萃取时间90min,解析釜压力6MPa。萃取结果采用高效液相色谱法(HPLC)进行分析,以得油率和五味子木质素含量为各地五味子的品质评价指标,并与有机溶剂法萃取所得木质素含量作对比。对于提取五味子精油,超临界CO2萃取法的精油品质明显优于有机溶剂萃取法。四地五味子中各种木质素的含量区域性差异显著,且吉林长白山北五味子的得油率和总木质素含量最高。
Schisandra Chinensis Baill from four places were extracted with superficial CO2 fluid extraction（SCDE） to explore the component differences based on regional.The condition of SCDE for Schisandra oil are：18 MPa extraction pressure 6 MPa,extraction temperature 40 ℃ and separate temperature for 90 minutes.The Schisandra oil were analyzed by high performance liquid chromatography（HPLC）,using the oil yield and the lignin content as the quality index of the Schisandra.The results will be compared with the results of organic solvent extraction.For the extraction of Schisandra oil,SCDE is superior to the organic solvent extraction.The component differences of the Schisandra oil from four different places are obvious,and the oil yield and the lignin content of Schisandra from Changbai Mountain in Jilin Province is the highest.
