黄芩(Scutellaria baicalesis Georgi)为常用清热解毒中药。其主要化学成分为黄芩甙等黄酮类化合物。因此许多含黄芩的中成药多采用黄芩甙作为质控指标。目前有关黄芩甙的测定方法有薄层扫描法,薄层色谱——分光光度法及紫外分光光度法。其中紫外法以其灵敏,简便快速,准确而成为许多中成药,尤其是液体制剂首选的含测方法。但据文献报道,紫外法测定黄芩甙尚存在一定问题。如采用药液直接测定往往其他成
Scutellaria baicalesis Georgi is commonly used as a detoxification medicine. Its main chemical composition is flavonoids such as astragalus. Therefore, many traditional Chinese medicines containing Astragalus use Astragalus as a quality control indicator. Current methods for the determination of jaundice include thin-layer chromatography, thin-layer chromatography, spectrophotometry, and ultraviolet spectrophotometry. Among them, the ultraviolet method is sensitive, simple, rapid, accurate, and becomes a preferred method for measuring many Chinese patent medicines, especially liquid preparations. However, according to reports in the literature, there are still some problems in the determination of Astragalus by UV method. If the use of liquid direct measurement often other
