摘　　要：目的采用三罐组动态逆流的方法对当归中阿魏酸的提取工艺进行优化。方法采用高效液相色谱法测定当归中阿魏酸含量,以阿魏酸为指标成分,采用全面试验考察提取时间和加水倍量对提取效率的影响。结果当归水溶性成分阿魏酸的优化提取工艺为:加10倍量水,单次提取时间为20 min。结论三罐组动态逆流的方法提取当归中阿魏酸的工艺可靠,提取效率高,节省能源。Objective To optimize technology of three can group dynamic countercurrentextraction process of ferulic acid from Angelicae Sinensis Radix. Methods The content of ferulic acidwas determined by HPLC. With content of ferulic acid as index, comprehensive test was used toinvestigate effect of extraction solvent and extraction time on extraction efficiency. Results Theoptimum process parameters were as follows：extraction solvent with 10 times of water;20minutes for each extraction time. Conclusion The process which uses method of three can group ofdynamic countercurrent extraction of ferulic acid from Angelicae Sinensis Radix is reliable, highlyefficient and energy saving.
