摘要
目的优选牛膝的最佳提取工艺。方法以牛膝总皂苷含量为评价指标,采用正交试验法筛选牛膝的最佳工艺条件。结果牛膝的最佳提取工艺条件为药材10倍量80%的乙醇,提取3次,每次1h。结论优化的提取工艺科学、合理,可以作为牛膝的最佳提取工艺方法。
Objective To optimize the extraction technology of Radix Achyranthis Bidentatae. Methods Orthogonal test was em- ployed for selecting the optimum of extraction technology with Achyranthis Bidentatae Saponins as the index. Results The optimal ex- traction technology of Radix Achyranthis Bidentatae was 80% alcohol with 10 times volume of drugs, and extraction time of 3 times with 1 h for each time. Conclusion The optimized extraction condition is reasonable and scientific for extracting Radix Achyranthis Bidentatae.
