水蒸气蒸馏法提取神香草精油的工艺研究

摘要

This article studied the technology extracted by hydro-distillation of essential oil of hyssop,liquid-solid ratio,MgSO4 concentration,the effect of extraction time on essential oil yield and quality,the best process condition was determined by orthogonal test,the factors of hyssopus officinalis essential oil yield effect was:Mg-SO4 concentration>extraction time>ratio of liquid to solid. Optimization of process conditions for the liquid to solid ratio 15∶1(mL/g),MgSO4 concentration 10 g/L,extraction time 2 h,hyssopus officinalis essential oil yield was 0.688%.%研究利用水蒸气蒸馏法提取神香草精油的工艺，分析了液固比、MgSO4浓度、提取时间对精油得率和品质的影响，通过正交试验确定最佳工艺条件，各因素对神香草精油得率影响程度是：MgSO4浓度＞提取时间＞液固比。优化的工艺条件为液固比15∶1（mL/g）、MgSO4浓度10 g/L、提取时间2 h，神香草精油得率为0.688%。
