薰衣草挥发油包合工艺的优化

[目的]优化薰衣草挥发油超声包合工艺,为薰衣草挥发油制剂的开发研究提供试验依据。[方法]以挥发油利用率为考察指标,采用单因素试验对薰衣草挥发油包合前溶解的乙醇浓度、乙醇用量进行考察;采用正交试验设计对薰衣草挥发油包合过程中各工艺参数进行优选。[结果]薰衣草挥发油最佳包合工艺：挥发油用85%乙醇按1∶25的比例溶解,油∶β-CD值为1∶10,β-CD浓度为12%,包合温度为55℃,超声包结时间为2.0 h。在最佳工艺条件下,薰衣草挥发油的利用率达到87.63%。[结论]该试验得到的包合工艺挥发油利用率高,操作简便,为薰衣草挥发油制剂的开发提供了试验依据。

Optimization of the Inclusion Process of Volatile Oil from Lavandula augustifolia Mill

[Objective] To optimize the inclusion process of Lavandula augustifolia Mill.volatile oil,so as to provide experimental basis for the developing and study of essential oil preparation products from Lavandula augustifolia Mill..[Method] Using utilization rate of volatile oil as an indicator,the concentration and use amount of ethanol employed to dissolve Lavandula augustifolia Mill.volatile oil were optimized by single factor test,and the inclusion process parameters were optimized by orthogonal test.[Result] With the proportion of 1∶25,85% ethanol was used to dissolve the volatile oil.The optimum inclusion conditions for lavender volatile oil were as follows:ratio of essential oil to β-CD of 1∶10,β-CD concentration of 12%,inclusion temperature of 55 ℃ and ultrasonic inclusion duration of 2.0 hours.Under the optimal inclusion process,the use rate of Lavandula augustifolia Mill.volatile oil reached as high as 87.63%.[Conclusion] Simple in operation,the inclusion process for Lavandula augustifolia Mill.volatile oil was high in utilization ratio,which provided experimental basis for the developing and study of essential oil preparation products from Lavandula augustifolia Mill..
