目的 对麦冬总皂苷的提取工艺进行优化。方法 以麦冬皂苷 D的含量为指标,采用正交试验法对麦冬提取的条件进行考察。结果 通过试验找出了麦冬提取的优化条件。麦冬用 5～ 10目药材,加 10倍量 80 %乙醇,热回流提取 3次,每次 1h。结论 此优选条件可充分提取麦冬总皂苷。

Object To optimize the best extraction of the total saponins in the root of Ophiopogon japonicus (Thunb.) Ker-Gawl.(RO).Methods The extract condition of total saponins in RO was observed by orthogonal design with ophiopogonis D as index.Results The optimum extract condition of RO was established.The more effective way was to smash RO to 5-10 mesh and extract total saponins in RO with ten times amount of 80% alcohol thrice by refluxing, one hour each time.Conclusion The total saponins in RO could be fully extracted in this condition.
