天然药物茵陈蒿(Artemisia Capillaris)常用于治疗黄疸。已知其含有利胆物质莨菪醚(Scoparone)和茵陈色原酮(Capillarisin)。为了评价其质量,作者曾报导了用紫外吸收法测定茛菪醚。茵陈色原酮由于存在干扰成分,用 TLC 亦不能分开,故不能用紫外吸收法测定。为此,作者根据茵陈色原酮与对二甲氨基桂皮醛(DACA)和 HCl 的特殊显色反应,建立了茵陈色原酮的比色测定法。本法专属性强,不受其它成分的干扰。且亦可用于复
The natural drug Artemisia Capillaris is commonly used to treat jaundice. It is known to contain Scoparone and Capillarisin. To evaluate its quality, the authors reported the determination of oxime ethers by ultraviolet absorption. Due to the presence of interfering components, capillaris is not separated by TLC and cannot be measured by ultraviolet absorption. To this end, the authors established a colorimetric assay for the chromophore of capillaria melanogaster based on a specific chromogenic reaction between capillarine and dimethylaminocinnamic (DACA) and HCl. This law is highly specific and is not interfered with by other components. And can also be used for complex
