青皮挥发油β-环糊精包合工艺优选

Study on Optimization for β-cyclodextrin Including Technology of Volatile Oils from Pericarpium Citri Reticulatae Viride

目的:用正交设计法优选青皮挥发油β-环糊精包合工艺的最佳条件。方法:用饱和水溶液超声法。结果:最佳工艺条件是油与β-环糊精之比为1∶8(mL.g-1),其次是乙醇体积分数为90%,超声时间30 min,超声时水温为40℃～45℃。结论:β-环糊精不同用量是影响青皮挥发油包合效果的主要因素,该工艺方法简单,流程短,适合工业化生产。

Objective ： To optimize the best β-cyclodextrin including technology conditions of volatile oil from Pericarpium Cirri Reticulatae Viride by orthogonal design. Method：The saturated aqueous solution-ultrasound method was used. Result：The optimum preparation conditions were established as follows：the proportion of volatile oil to β-cyclodextrin was 1 ： 8 （ mL. g ^- 1 ） , The concentration of alcohol was 90 % , The ultrasonic time was 30 min, The water temperature was at 40 ℃-45 ℃. Conclusion：The different usage of β-cyclodextrin is the principal factor that in- fluence the inclusion effect of volatile oil from Pericarpium Citri Reticulatae Viride,the method of this technology is simple, and the technological process is short, it is suitable for commercial process.
