【摘要】 目的确定虎杖、当归的最佳醇提工艺条件。方法以浸膏得率和虎杖苷浸出量为指标,对影响浸出的主要因素进行优化。结果最佳的提取工艺条件为:加60%的乙醇回流提取2次,加醇量分别为10、8倍,提取时间分别为1.5、1.0h。结论优选的提取工艺可为工业化生产提供实验依据。更多还原

【Abstract】 Objective To ascertain the optimum condition for extracting Rhizoma polygoni cuspidati and Radix angelicae sinensis with alcohol. Method With extract yield and the amount of polydatin as index,the primary factors of affecting the extraction were optimized. Result The optimum extraction condition was as follows:taking 60% alcohol as solvent,the meterials were refluxed and extracted two times with 10 and 8 times volume of alcohol for 1.5 h and 1.0 h,respectively. Conclusion The optimum extraction process provides an experimental basis for industrial production.更多还原
