藏药白亮独活的质量标准研究

Study on the Quality Standards of Tibetan Medicine Bailiang Duhuo

目的为了更好地规范和控制藏药白亮独活的质量,对其进行质量标准研究,为白亮独活的质量控制提供科学的依据。方法参照《中华人民共和国药典》2020年版中规定的相关方法,对白亮独活药材的性状、显微特征以及各检查项进行检测;采用薄层色谱法,以硅胶G为薄层板,石油醚(60~90)-乙酸乙酯(3:1)为展开剂,欧前胡素为对照品,建立其薄层鉴别方法。结果准确描述了藏药白亮独活的显微鉴别特征和薄层鉴别特征。其水分为9.9%~11.0%,总灰分为5.4%~9.1%,酸不溶性灰分为0.79%~4.98%,水溶性浸出物的含量为30.71%~38.83%.结论该研究首次全面考察了西藏地区白亮独活药材的各项质量指标,能有效评价其质量。

Objective In order to better standardize and control the quality of Tibetan medicine Bailiang Duhuo,the quality standards were studied so as to provide a scientific basis for its quality control.Methods Referring to the rel-evant methods specified in the 2020 edition of the Pharmacopoeia of the people's Republic of China,the characters,microscopic characteristics and inspection items of Bailiang Duhuo medicinal materials were detected.The thin-layer chromatography(TLC)method was used to establish a thin-layer identification method with silica gel G as the thin-layer plate,petroleum ether(60-90)-ethyl acetate(3:1)as the developing solvent,and imperatorin as the reference substance.Results The microscopic identification characteristics and thin-layer identification characteristics of Ti-betan medicine Bailiang Duhuo were described accurately.Its moisture content is 9.9%-11.0%,the total ash is 5.4%-9.1%,the acid-insoluble ash is 0.79%-4.98%,and the content of water-soluble extract is 30.71%-38.83%.Conclusion This study was the first to comprehensively investigate the quality indexes of Bailiang Duhuo medicinal materials in Xizang,and its quality could be effectively evaluated.
