摘　　要：目的:探讨正交试验优选地榆总鞣质提取工艺。方法:采用正交实验法,以地榆总鞣质的含量为提取工艺评价指标,以正交设计表考察乙醇浓度、回流时间、溶剂倍数和回流次数各个因素对提取工艺的影响。结果:地榆加80%乙醇,溶剂10倍,回流2次,每次回流1 h。结论:提取工艺条件合理可行。Objective：To optimize the extraction condition of total tannins of sanguisorba officinalis L. Methods： Orthogonal design were used to evaluate the extraction efficacy. Result ： The optimum conditions were as follows ： total tannins sanguisorba officinalis L are extracted by 80% alcohol, 10 times of decoction for 4 time, each time for 1 hour. Conclusion：The method is suitable for extraction of total tannins from Sanguisorba officinalis L.
