Using orthogonal experiment design, the total saponin constituents were obtained by refluxing extraction with alcohol and separated by macroporous adsorption resin and n-Butyl alcohol from the stem bark of Kalopanax septemlobus. According to the purity analysis and the yield, the extraction process was optimized. The results showed that the main saponin constituents were gained with a yield of 1.32% by using macroporous adsorption resin but 1.05% by using n-Butyl alcohol. The former was more efficient than the latter on both yield and color. The optimal process with isolation by macroporous adsorption resin is cheap, simple and practical.
采用正交试验设计，以刺楸茎皮为原料，通过乙醇回流提取、大孔吸附树脂及正丁醇分离得到总皂苷成分。根据纯度分析和得率对提取工艺进行优化。结果表明，大孔吸附树脂法总皂苷得率为1.32%，正丁醇法为1.05%。大孔吸附树脂法在得率和色泽方面均优于正丁醇法。大孔吸附树脂分离的最佳工艺价廉、简便且实用。
