Abstract:
Objective To set up the technology for adsorbing and separating total flavone in Sarcandra glabra with macroporous adsorption resin,11 types of macroporous adsorption resins were investigated.Methods The static adsorption and separation were used in investigation of macroporous adsorption resin;the dynamic adsorption and separation were used in studying the condition of adsorption and separation.The total flavone adsorption capacity,total flavone content,and total flavone recovery rate were used as the evaluation criteria.The UV spectrophotometric method was used in the determination of total flavone content.Results The results showed that among 11 types of macroporous adsorption resins,the HPD400 was the best for adsorbing and separating the total flavone in S.glabra in the following technological condition: the concentration of S.glabra sample extract was 10 mg/mL;the maximum adsorbing capacity for total flavone in S.glabra was 9.5 mg/mL;the current velocity was 2.5 mL/min;the eluting reagent was 70% ethanol(three times as the volume of the resin);and the HPD400 resin could be used three times,repeatedly.Conclusion It is a simple and efficient to separate the total flavone in S.glabra under the technological conditions,and a total flavone recovery rate is about 85%.
