| Abstract: | Aim To study the extract method of effective ingredient emodin in polygonum cuspistum.Method The content of emodin in polygonum cuspistum was determined by HPLC.We inspected the effect of different alcohol concentration,extract time and the flow rate for the content of emodin in extractum polygonum cuspistum with orthogonal trial.Results The yield rate of the extractum polygonum cuspistum and the content of emodin is the most effective degree while the condition is 70% alchol concentration,36 h each time for extraction.Conclusion It is most significant that alcohol concentration and extract time have an effect on the yield rate of the extractum polygonum cuspistum and the content of emodin.The flow rate is of little importance. |
