本文介绍了由制首乌制成首乌片的生产全过程中,所含蒽醌类成分的含量测定。其中的游离蒽醌系将供试品在索氏提取器内用氯仿提取,提取液用5%NaOH-2% NH_4OH混合液提取比色,以1,8-二羟基蒽醌为标准;结合蒽醌则先用5NH_2SO_4水解,迴流3小时,再加氯仿迴流提取数次,至提尽为止,合并氯仿液,同上以混合碱液提取后进行比色测定。
This article describes the determination of the content of anthraquinones contained in the whole production process of Shouwu Tablets made from Radix Scutellariae. Among them, the free terpenoids were extracted with chloroform in the Soxhlet extractor, and the extracts were extracted with a mixture of 5% NaOH-2% NH 4OH, using 1,8-dihydroxyanthraquinone as the standard; The hydrazine was first hydrolyzed with 5NH 2 SO 4 , refluxed for 3 hours, and extracted several times with chloroform. Until the extraction was complete, the chloroform solution was combined and colorimetric determination was performed after extraction with the mixed lye.
