| 摘 要： | 目的研究大黄中大黄素的提取工艺。方法以大黄素含量为指标,正交实验法考察提取时间、乙醇浓度及用量对大黄素提取率的影响。结果提取时间、乙醇浓度及用量对大黄素提取率的影响有显著影响。结论最佳提取工艺为:大黄用8倍量60%乙醇,浸泡12 h,渗漉提取12 h,大黄素含量最高。

| Abstract: | Objective To optimize the extraction of emodin from rhubarb.Methods With the content of emodin as index,the percolation time,different concentrations of alcohol and the amount of solvent were investigated by orthogonal design to detect their influences on the extraction rate of rhubarb.Results The significant effects of percolation time,alcohol concentration and alcohol volume on the extraction of emodin content were discovered.Conclusion The optimum rhubarb percolation condition obtained is adding 8-fold t... |
