桂枝和肉桂混合挥发油的包合工艺研究

Research for P-cyclodextrin inclusion of essential oil from Cinnamomi Ramulus and Cinnamomi Cortex

目的:考察桂枝和肉桂混合挥发油的包合条件。方法:采用正交试验,以挥发油利用率、包合物含油率及包合物收率为包合工艺的综合评价指标。结果:挥发油包合的最佳工艺为:采取饱和水溶液法,油β-环糊精1∶8,包合温度50℃,包合时间60min。结论:桂枝和肉桂混合挥发油的包合工艺合理可行。

Objective：To investigate the inclusion conditions of essential oil from Cinnamomi Ramulus and Cinnamomi Cortex.Methods：The study was carried out with orthogonal experiment.With the utilization rate of essential oil,oil rate in inclusion and the recovery of inclusion as the comprehensive index of inclusion process.Results：The optimal inclusion conditions were：applying the saturated aqueous solution method,oil to β-CD：1：8,inclusion temperature：50℃,inclusion time：60 min.Conclusion：The inclusion processes for mixed essential oils is steady and feasible.
