摘　　要：以精油得率为指标,采用单因素实验和正交实验对超声辅助水蒸气蒸馏提取硬尖神香草精油的工艺条件进行了优化,确定最优工艺条件为:超声频率60 kHz、超声时间30 min、料液比1∶6(g∶mL)、提取时间3 h,在此条件下,精油得率为1.37%。与常规水蒸气蒸馏法(1.12%)相比,超声辅助水蒸气蒸馏提取硬尖神香草精油的得率提高了22.32%,且时间短,操作简单,适合规模化生产。Taking the yield of essential oil as an index,we optimized the ultrasonic-assisted hydro-distillation extraction process of essential oil from Hyssopus cuspidatus Boriss.by single-factor experiments and orthogonal experiments.The optimum extraction conditions can be determined as follows:the ultrasonic frequency of 60 kHz,the ultrasonic time of 30 min,the solid-liquid ratio of 1∶6(g∶mL),and the extraction time of 3 h.Under above conditions,the yield of essential oil can reach 1.37%.Compared with the yield extracted by the conventional hydro-distillation method(1.12%),the yield of essential oil extracted by ultrasonic-assisted hydro-distillation increases by 22.32%.In addition,the ultrasonic-assisted hydro-distillation method has the advantages of short time and simple operation,which is suitable for large-scale production.
