利用微波萃取技术针对某中药厂双黄连制剂生产过程中产生的废弃黄芩提取药渣进行了有效成分的再次提取并同传统水提工艺进行了对比。以有效成分（黄芩苷）收率做为考察指标，用正交设计结合单因素分析方法考察微波提取黄芩苷的最佳提取条件，旨在探讨植物药提取废渣的再利用价值、探寻植物药提取废渣资源化的有效途径。结果表明：各因素对黄芩苷收率的影响依次为：乙醇浓度>粒径>功率>提取时间，其中乙醇浓度为显著性影响因素，最佳工艺为：以30%乙醇作为提取溶剂，黄芩药渣粒径80目，微波功率选择500W，微波提取2min。与水提工艺相比，在最佳工艺条件下，微波提取工艺能够获得较高收率的黄芩苷。

Extracting active component from Chinese herbal medicine extractive residue which came from a traditional Chinese medicine plant was carried out by means of microwave-assisted extraction and the technique was compared with the traditional one (aqueous extraction). In order to discuss the recycle value of extracting from the extracted Chinese herbal residue, and to seek for the efficient path for recycling of Chinese herbal residue, the process for extracting baicalin was optimized with using yield of baicalin as the investigation index by means of single factor analysis and orthogonal experiments. The results showed influence factors on baicalin yield as follows(form great to less):ethanol concentration>granularity of ex-tractive residue>microwave power>duration of microwave irradiation. And the ethanol concentration was the significant influencing factor. The opti-mal parameters were obtained as follows:30%ethanol was chosen as the extraction solvent;the microwave power was 500W;the granularity of the ex-traction residue was 80 meshes;the duration of microwave irradiation was 2min. The higher yield of baicalin could be achieved by microwave-assisted extraction.
