目的 优化β-环糊精包合加减当归芍药散(modified Danggui Shaoyao San,MDSS)中挥发油的最佳工艺。方法 采用熵权法确定包合物得率及挥发油包合率的权重系数,以综合评分为指标,β-环糊精与挥发油的比例、包合温度、包合时间作为包合工艺的关键参数,采用正交试验优化包合工艺,通过薄层色谱、紫外光谱、红外光谱、X射线衍射、扫描电镜对包合物进行表征。结果 挥发油包合的较优工艺为挥发油与β-环糊精(1:10)在包合温度为40℃的条件下,包合2 h。经验证,包合物得率为64.56%,挥发油包合率为80.44%。挥发油包入β-环糊精空腔中,包合物制备成功。结论 该工艺可用于MDSS挥发油的包合,可为后续深入研究奠定基础。

Objective To optimize the β-cyclodextrin inclusion process for volatile oil of modified Danggui Shaoyao San (MDSS). Methods Taking the ratio of β-cyclodextrin to volatile oil, inclusion temperature, and stirring time as the factors, the inclusion process conditions were optimized by orthogonal test. The weight coefficients of inclusion compound yield and volatile oil inclusion rate were determined by entropy weight method, and the inclusion complex was verified by thin layer chromatography, UV spectroscopy and infrared spectroscopy. The inclusion compounds were characterized by thin-layer chromatography, ultraviolet spectroscopy, infrared spectroscopy, X-ray diffraction, and scanning electron microscopy. Results The optimal conditions were determined to be 10:1 for β-cyclodextrin-volatile oil ratio, 40℃ for in clusion temperature, and 2 h for stirring time, the inclusion rate and yield were 80.44% and 64.56%, respectively. The inclusion of volatile oils into β-cyclodextrin indicated that inclusion compounds were successfully prepared. Conclusion This stable and feasible method can be used for the inclusion of volatile oils of MDSS and it can lay the foundation for follow-up in-depth research.
