摘要 优化当归中挥发油的提取工艺,以当归中挥发油的得率为衡量指标,采用单因素实验考查浸泡时间(A)、提取水量(B)、提取时间(C)3个因素对当归中挥发油得率的影响,用L_(9)(3^(4))正交试验优化当归中挥发油的提取工艺。正交试验的优化结果表明,浸泡时间为4 h,提取水量倍数为10倍,提取时间为6 h时为最佳工艺,当归中挥发油的得率为0.50%。优化后的方法稳定性好,可用于中药材挥发油的测定,填补中药没有指定测定挥发油含量方法的空白。 The extraction process of volatial oil from angelica sinensis was optimized.The extraction yield of volatile oil from angelica sinensis was taken as the index.The effects of soaking time(A),extraction water(B)and extraction time(C)on the yield of volatile oil were investigated by single factor experiment.Optimization of extraction technique of volatile oil from angelica sinensis was made by L_(9)(3^(4))orthogonal test.The results showed that the optimal process was 4 h immersion time,10 times extraction water multiple,6 h extraction time,and the yield of volatile oil from angelica sinensis 0.50%.The optimized method has good stability and can be used for the determination of volatile oil in traditional Chinese medicine,filling the gap of no specified methods for determining the content of volatile oil in traditional Chinese medicine.
