摘要
采用溶剂浸提法考察乙醇浓度、水浴温度、提取时间、料液比等单因素对竹节参中总皂苷提取率的影响。然后运用正交分析法确定最佳提取条件为:乙醇的浓度为60%,提取时间为4.0h,温度为80℃,料液比为1∶30(g/mL)。并通过实验确定在此条件下总皂苷提取率达到了10.04%。
The extraction of total saponins from the Panax japonicus was studied in thin paper,focusing on the ethaol concentration,water temperature,extraction time and material liquid ratio for single factors.The optimum conditions for the orthogonal analysis are 60% ethanol with material liquid ratio for 1∶30（g/mL） in 80℃ temperature for extraction reflux 4.0h.The extraction rate under the optimum conditions discussed above is 10.04%.
