黄芩饮片的产地加工方法研究

目的:对黄芩不同干燥状态切制的方法进行考察,并与传统饮片进行比较,探讨黄芩产地加工的可行性。方法:测定黄芩的含水量并切制饮片,HPLC比较测定各饮片中有效成分黄芩苷、黄芩素的含量及醇溶性浸出物含量。结果:药材含水量在28%～42%时,不仅易于直接切制饮片,且饮片无变绿现象,浸出物及黄芩苷、黄芩素含量与传统方法炮制的黄芩饮片相近,可以作为黄芩饮片产地加工炮制的工艺条件。结论:产地加工炮制方法可简化饮片生产流程,有效地避免因黄芩苷水解导致的饮片变绿现象,减少有效成分的流失,保证饮片质量。

Study on Habitat Processing Method of Scutellaria baicalensis

Objective: Discussing the feasibility of habitat processing method of Scutellaria baicalensis compared with traditional processing method. Method: The moisture content of medicinal parts was determined before processing, and the alcohol-soluble extract content and the content of baicalin and baicalein were compared on different pieces. Result: It was easily to cut pieces with non-green phenomenon when the moisture content was in 28%-42%. The content of baicalin, baicalein and alcohol-soluble extract were similar to the traditional processing method. Conclusion: The habitat processing method not only simplifies the processing method but also avoid the hydrolysis of baicalin more effectively. It can also reduce the loss of active ingredients to ensure the quality of S.baicalensis.
