白芍中芍药苷的提取工艺研究

摘要

Percolation method is used to extract paeoniflorin from Paeonia lactiflora Pall. Referring to the content of Paeoniflorin, orthogonal design was applied for optimum extraction process. The orthogonal experiment, the optimum extraction process conditions: soaking 24 hours in 15 volumes 70% ethanol percolation process can get a higher extraction rate of paeoniflorin.%采用渗漉法对白芍中芍药苷进行提取，以芍药苷为指标，用正交试验采用3因素3水平对工艺进行优化，得到的较佳工艺条件为浸渍24 h，用15倍体积70%的乙醇渗漉提取可以获得较高的芍药苷提取率。
