摘　　要：目的:优化当归挥发油的提取工艺。方法:采用L9(34)正交试验,以当归挥发油得率为指标,优选当归挥发油的水蒸汽提取工艺。结果:最佳提取工艺条件为当归粉碎度10目,加水量10倍,浸泡3 h,提取8 h。并开展验证实验,得到挥发油的提取率为0.5%。结论:该工艺简便可行,可用于当归挥发油的提取。This study was aimed to optimize the extraction of volatile oil in Radix Angelicae Sinensis. The L9（3^4） orthogonal design was carried out for the optimization of water extraction of volatile oil in Radix Angelicae Sinensis. And the content of volatile oil was used as reference index. The results showed that the optimal extraction process was as follows. Medicinal materials were crashed to go through mesh 10, then were soaked in 10-fold volume of water for 3 hours, and were extracted for 8 hours. It was concluded that the optimal extraction technology is simple and feasible with the extraction rate of volatile oil being 5.0%.
