摘　　要：目的:本文优选出五味子浸膏的最佳提取工艺。方法:用均匀设计法安排实验,以分光光度法测出的浸膏中总木脂素的含量为参考指标,考察乙醇浓度、回流时间、溶媒用量与提取次数对总木脂素提取率的影响。结果:确定乙醇浓度90%,回流时间3小时,溶媒用量4倍,提取两次为最佳提取工艺。结论:实验证明本工艺稳定可行,能作为提取五味子浸膏生产工艺参考。Objective：This article optimized the best extracting technology of Chinese magnoliavine fruit extract.Methods：Uniform Design arrange the experiment,with Spectrophotometry to determine the total lignanoid in Chinese magnoliavine fruit extract for reference index,investigate the affection of alcohol density、backstreaming time、dissolvant dosage、abstraction frequency.Results：Determin alcohol density90%,backstreaming time 4hour,dissolvant dosage 4times,abstraction twice to be the best craft.Conclusion：This experiment proofs the technology is stable,can do Chinese magnoliavine fruit extract production technology reference.
