摘要
目的:确定提取苦玄参皂苷的工艺条件。方法:采用正交试验法,以苦玄参总苷和苦玄参苷ⅠA、ⅠB的含量为考察指标进行提取工艺优选。结果:最佳提取工艺为:用20倍量70%乙醇浸泡3h,于80℃回流提取2次,提取用时第一次3h,第二次1h。结论:优选出的工艺简便,实用,准确度高。该工艺可用于生产参考。
Objective：To study the optimum extraction conditions of triterpenoid saponins from Picria felterrae.Methods：The optimum extraction conditions were investigated by the contents of the total glycosides and picfeltarraenine I A and I B,using orthogonal test Results：The optimum extraction conditions were as follows：using 70%alcohol of 19 times than the amount of original material soaking 3 hours,extracting twice with hot reflux method at 80℃,3h the first time,1h the second time.Conclusion：The selected extraction conditions are convenient and practical with high accuracy,and could be used as a reference for industrial production.
