【摘要】目的:优选岩白菜中岩白菜素最佳提取工艺并考察其纯化方法.方法:用紫
外-可见分光光度计测定岩白菜素的含量为指标,考察了影响大孔吸附树脂纯化及醇提工艺的主要因素.结果:确定岩白菜的最佳提取工艺条件为10倍量50%的乙醇,回流提取3次,每次0.5h,最佳的纯化条件为每克D-101树脂(干重)最大上样量2.5g 原生药材,上样静置吸附30min后用6倍柱床体积20%的乙醇洗脱.结论:在该提取及纯化的最佳参数组合下,岩白菜素的含量达14.023%,结果可靠.%Objective : To optimize the best Extraction process and to investigate its Purification Technology of Bergenin from the Bergama purpurascens (Hook.f.et Thoms.) Engl.Methods: To determine Bergenin content with UV - visible spectrophotometer as an indicator to study the main effect factors of influencing macro reticular resin purification and ethanol extract Lechnology.Results: Having determined the optimal extraction process of Bergama purpurascens (Hook.f.et Thoms.) Engl., which include extraction Bergama purpurascens (Hook.f.et Thoms.) Engl.with tenfold 50％ ethanol three times, 0.5 hour per time, and best purification condition is that loading 2.5 grams net raw medicinal materials at most into D - 101 resin each gram and absorb 30mins and the procedure of elution is 6 times 20％ethanol the volume of colume.Conclusion: the content of Bergenin reached
14.023％ , which based on The best parameters of purification and extraction, the results are reliable.
