摘要
目的优选出车前草总三萜(TTP)的最优提取纯化工艺。方法用紫外分光光度法测定总三萜含量,以TTP提取率作为检测指标,正交法优选最佳的提取纯化工艺。结果 TTP最佳的提取工艺为8倍量的95%乙醇提取,提取2次、每次1 h。结论优选的提取纯化工艺操作简单、稳定可行、重复性好。
Objective To optimize the extraction technology for total triterpenoids from Plantago depressa Willd.（ TTP）.Methods To determine the content of total triterpenoids,the optimum extraction condition was investigated by orthogonal design. The extraction quantity was regarded as the detection index. Results The optimum extracting condition was adding8 times amount of 95% alcohol and refluxing twice,1 h once. Conclusion The optimum technology is stable and feasible and had good application prospect.
