Study on the Purification and Extraction Technology of Bergenin from the Bergama purpurascens (Hook.f.et Thoms.) Engl
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.
