摘要
目的:研究天麻药材中天麻素的最佳提取工艺。方法:以天麻素含量为评价指标,采用正交试验设计对提取方法、提取溶剂、溶剂用量进行考察,确定最佳提取条件。结果:最佳提取条件为:以体积分数50%乙醇为提取溶剂,加入药材20倍溶剂量,超声提取1 h。其中提取方法影响因素最大。结论:本研究确定的提取工艺天麻素提取率高,操作简便易行,稳定可行。
Objective :To optimize the extraction process of gastrodin in Tianma (Gastrodia elata B1. ). Methods:Taking the content of gastrodin as the evaluation index, extraction method, extraction solvent and solvent dosage were investigated in orthogonal experiment. Results:The best condition:50% volume ethanol as extraction solvent,20 times herbs, ultrasonic extraction for 1 h. The factor of extrac- tion method had significant influence on the extraction. Conclusion:The established extraction process has higher extracting rate and is simple, stable and feasible.
