目的 優(yōu)選仙慈丹處方藥材的提取工藝。方法 以干浸膏得率和野黃芩苷的保留率為評價指標(biāo)，高效液相色譜法定量，采用L9(34)正交試驗對仙慈丹水提取工藝進行優(yōu)化。結(jié)果 仙慈丹的最佳提取工藝為：水回流提取3次，每次0.5 h，溶媒倍量分別為12、10、10倍。結(jié)論 該提取工藝參數(shù)穩(wěn)定、可行，適用于仙慈丹處方藥材的提取。

Objective To optimize the extract process for Xiancidan prescription. Methods Dry extract yield and the retention rates of scutellarin were used as indexes, HPLC was used to quantify, and the effects of extraction time, the amount of water, extracting times, and degree on extraction technology were evaluated by L9(34) orthogonal test. Results The optimum technical parameters of the water extracting technology were as follows: circumfluence extracting for 3 times with 12, 10, and 10 times the amount of water, 0.5 h per time. Conclusion The preparation procedure is stable and feasible and it can be used for the extraction of Xiancidan prescription.
