本文采用单因素试验，运用紫外分光光度法作为黄芩苷的分析方法，对黄芩苷的水提工艺的影响因素进行了考察，并在此基础上进行正交实验，优化提取工艺参数。结果表明，当破碎度为块状，加水量为药材重量的8倍，煎煮3次，每次1.5 h时，黄芩苷的提取效果最好，提取率为23.0491%。

The effects of several influential factors on the water extraction of baicalin were investigated by single factor experiment using UV-spectrometry for the determination of baicalin content. The extraction conditions were further optimized by orthogonal design. Results showed that, when the materials were crushed into pieces, the best water-solid ratio, reflux extraction times and the extraction time per times were 8, 3, and 1.5 h, respectively, under which the extraction yield reached 23.0491%.
