摘要
目的:探索黄芪甲苷的新型提取方法。方法:采用新型连续循环提取装置提取黄芪甲苷,以甲苷含量为筛选指标,采用正交试验考察新提取方法的提取条件,优选出最佳提取工艺。结果:提取黄芪甲苷新方法的最佳条件:溶剂循环3个周期,提取温度40℃,蒸馏时间3h。结论:该提取新方法值得推广。
OBJECTIVE To explore a new extraction method of astragaloside Ⅳ from Astragalus root via continuous circular extraction method. METHODS L9（4^3 ） orthogonal design was used. RESULTS The best extraction condition was as follows： 3 solvent cycles 45 ℃ of extraction temperature, and 3 h of extraction time. CONCLUSION The method is easy to poerate and has good reproducibility.
