摘　　要：以安徽黄山产阴干薄荷(Mentha canadensis Linnaeus)叶为原料,利用水蒸气蒸馏法对薄荷挥发油的提取工艺进行优化,对料液比、提取时间、浸泡时间、超声时间4个影响因素进行研究。结果表明,在料液比1∶11(g∶mL)、提取3.0 h、浸泡时间2.0 h、超声30 min为最佳提取工艺。在此最佳提取工艺下,挥发油的平均提取率为2.3%。验证试验也表明,该薄荷挥发油提取工艺稳定、可靠。The extraction technology of volatile oil of mint(Mentha canadensis Linnaeus)was optimized by steam distillation with the raw material of mint leaf produced in Huangshan,Anhui province.The effects of four extracting factors(solid-liquid ratio,distillation time,soaking time and ultrasonic time)were used.The results showed that the best extraction technology was the solid-liquid ratio 1∶11(g∶mL),distillation time 3.0 h,soaking time 2.0 h,and the ultrasonic time 30 min.Under the condition,the average extraction rate of volatile oil was 2.3%.The verification test also showed that the extraction process of volatile oil from mint was stable and reliable.
