目的：研究黄藤中黄藤素的提取和分离方法，进而以黄藤素为原料制备延胡索乙素。方法：采用L9（34）正交试验优化黄藤素的提取方法；采用大孔树脂层析技术研究黄藤素的分离方法；采用硼氢化钠氢化黄藤素的反应制备延胡索乙素。结果：10倍量（v/w）50%乙醇回流提取3次，每次2 h，获得黄藤素的含量为36.40%，收率为3.17%；使用HPD-300大孔树脂吸附，纯化水、20%、60%乙醇溶液梯度洗脱分离，得到黄藤素含量为65.47%，收率为82.44%；氢化制得延胡索乙素含量为98.31%，收率为72.04%。结论：此方法可制得较高含量和收率的黄藤素，用此原料能制得较高含量和收率的延胡索乙素。

This study was aimed to extract and separate fibrauretine from Chinese herbal medicine Fibraurea recisa Pierre. and to prepare tetrahydropulmatine with fibrauretine. Extraction method of fibrauretine were optimized by the L9(34) orthogonal arrays as experimental designs. Then, elution chromatography method was studied with the macroporous adsorption resin chromatography technology. At last, tetrahydropulmatine was prepared by the reaction of sodium borohydride hydrogenating fibrauretine. The results showed that the content and yield of obtained fibrauretine were 36.40% and 3.17%, respectively. The reflux exacted methods of fibrauretine were with 10 times amount (v/w) of 50% ethanol solution for 2 hours and 3 times. Then, HPD-300 macroporous resin was used to absorb fibrauretine, and purify water. The 20% and 60% ethanol solution was used for elution. The content and yield of obtained fibrauretine were 65.47% and 82.44%, respectively. And the content and yield of obtained tetrahydropulmatine were 98.31% and 72.04%, respectively. It was concluded that the method can obtain fibrauretine with relative high content and yield. Using this material can obtain tetrahydrofibrauretine with relative high content and yield.
