摘　　要：目的 :通过对单味当归、单味川芎及复方当归和川芎在不同工艺条件分别萃取结果的比较 ,考察提取率的变化规律。又对超临界油的溶解度进行了数据关联。方法 :超临界萃取法 ;气相色谱分析法 ;Chrastil方法拟合数据。结果 :复方产物的提取率明显高于单味产物提取率之和。结论 :超临界CO2 萃取中 。Objective: To study the regularity of extraction rate by comparing the extraction results between the compound and the individual traditional Chinese medicine, treating the solubility data by using Chrastil equation.Methods: SCCO 2 extraction, GC analysis, Chrastil equation.Results: The extraction rates of compound are clearly greater than the sum rates of individual angelica and ligusticum.Conclusion: The extraction rates of compound do not simply equal the sum of rates of individual angelica and ligusticum.
