目的:优选藏茴香挥发油的提取与包合工艺。方法:以加水量、提取时间、浸泡时间为因素,挥发油提取量为指标,通过正交试验优选挥发油提取工艺;以挥发油与β-环糊精(β-CD)的比例、包合温度、包合时间为因素,挥发油利用率、包合率、综合评分为指标,通过正交试验优选挥发油包合工艺。结果:最佳挥发油提取工艺为加6倍量水浸泡0.5 h,提取挥发油4 h;最佳挥发油包合工艺为挥发油与β-CD的比例为1∶8(V∶m),30℃下搅拌包合2 h。结论:优选的挥发油提取与包合工艺合理、可行,可用于藏茴香挥发油的提取与包合。

OBJECTIVE： To optimize the extraction and inclusion technology of volatile oil from Carum carvi. METHODS： The extraction technology of volatile oil was optimized by orthogonal test with amount of water, extraction time and immerse times as factors using extraction of volatile oil content as index. The inclusion technology of volatile oil was optimized by orthogonal test with the ratio of volatile oil to β-cyclodextrin （β-CD）, inclusion temperature and inclusion time as factors using utilization ratio of volatile oil and the yield of inclusion compound and Comprehensive score as index. RESULTS： The optimized extraction technology was as follows： 6-fold water, soaking for 0.5 h, extracting for 4 h. The optimal inclusion technology was as follows： ratio of volatile oil to β-CD 1：8（ V： m）, at 30℃, lasting for 2 h. CONCLUSIONS： The optimal extraction and inclusion technology is reasonable and feasible, and can be used for the extraction and and inclusion of volatile oil from C. carvi.
