超声强化水蒸气蒸馏提取神香草精油的工艺

Extraction Process of Hyssopus Essential Oil by Ultrasonic Strengthen Combined with Hydro-distillation

研究利用超声强化水蒸气蒸馏法提取神香草精油的工艺,分析超声强化时间、超声功率、液固比、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:超声功率>超声强化时间>提取时间>液固比。优化的工艺条件为超声功率160 W、超声强化时间15 min、液固比15∶1(m L/g)、提取时间1 h,神香草精油得率为0.738%

Studied the technology was extracted by ultrasonic strengthen combined with hydro-distillation of essential oil of hyssop. Analysised effect of penertration time, ultrasonic power,liquid-solid ratio,extraction time on essential oil yield and quality,the best process conditions were determined by orthogonal test. The factors of hyssopus officinalis essential oil yield effect were： ultrasonic powerpenertration time extraction timeratio of liquid to solid. Optimization of process conditions for the ultrasonic power 160 W,penertration time 15 min,liquid to solid ratio 15 ∶ 1（m L/g）,extraction time 1 h,Hyssopus officinalis essential oil yield was 0.738 %.
