摘要
[目的]优选密花香薷精油最佳提取工艺条件。[方法]采用超声辅助水蒸气蒸馏,通过正交试验考察了药材粒度、超声时间、料液比、浸泡时间4因素3水平对密花香薷精油得率的影响。[结果]密花香薷精油提取的最佳工艺条件为药材粒度50目,超声时间12min,浸泡时间6 h,料液比1∶16 g/ml。在该工艺条件下,精油的平均得率为0.407%。[结论]优选的密花香薷精油提取工艺得率较高,条件合理,简单可行。
[Objective] The study aims to optimize the extracting technology conditions of essential oil from Elsholtzia densa Benth.[Method] Volatile oil was extracted from Elsholtzia densa Benth using steam distillation,and the effects of four extracting factors（the size of the medicinal herb,ultrasonic time,soaking time and the ratio of the material to liquid） on the yield of essential oil extracted from Elsholtzia densa Benth was analyzed through the orthogonal test method.[Result] The optimized extraction process of essential oil from Elsholtzia densa Benth was as follows： the size of the medicinal herb 50 mesh,ultrasonic time 12 min,being soaked in the water for 6 h,and the ratio of the material to liquid 1∶16 g/ml.Under this conditions,the average extracting rate of the essential oil was 0.407%.[Conclusion] The optimized extraction process of essential oil from Elsholtzia densa Benth was simple and practicable,and its extracting rate was higher.
