目的优选清解颗粒挥发油的提取和β-环糊精包合工艺。方法采用水蒸馏法进行提取,以提取时间、粉碎度、加水倍数为考察因素,挥发油体积为评价指标,考察清解颗粒挥发油的提取工艺;以包合率为评价指标,采用单因素试验和Box-Behnken响应面法结合,优选最佳包合工艺。结果优选的提取工艺为荆芥、防风、连翘药材粗粉加10倍量水,提取3 h。包合方法为饱和水溶液法,包合工艺为挥发油与β-环糊精的投料比为1∶12、包合温度40 ℃、包合时间3.5 h。通过薄层色谱法、紫外光谱法和红外光谱法初步证明了清解颗粒挥发油包合物的生成。结论优化的清解颗粒挥发油提取和包合工艺稳定可行,可用于工业化大生产。

Objective To optimize the extraction of volatile oil from Qingjie Granules and process of inclusion compound of beta-cyclodextrin. Methods Water Distillation was used for extraction. Extraction time, grinding degree, and the amount of water were set as inspection factors, and volatile oil volume was set as the evaluation index to inspect extraction process of volatile oil from Qingjie Granules. With inclusion rate as the evaluation index, the single factor test and the Box-Behnken combined with the response surface method were used to choose th...
