采用超临界流体萃取(SFE)技术和CGC技术测定了中药补骨脂中的补骨脂素和异补骨脂素。对超临界流体萃取过程中影响萃取效率的主要因素采用正交设计法和方差分析法进行了考察,确定了主效应和适宜的操作条件。与传统的萃取法比较,SFE具有经济、快速、简便、选择性好、环境污染小等优点。
The psoralen and isopsoralen in Chinese psoralen were determined by supercritical fluid extraction (SFE) and CGC techniques. The main factors influencing the extraction efficiency in the process of supercritical fluid extraction were investigated by orthogonal design and analysis of variance (ANOVA), and the main effects and suitable operating conditions were determined. Compared with the traditional extraction method, SFE has the advantages of economy, rapidity, simplicity, good selectivity and low environmental pollution.
