晕宁颗粒的薄层鉴别研究

Study on TLC identification of vertigo-calming granules

目的为了改善和提高医院制剂晕宁颗粒的质量标准,对其进行实验研究,以建立可操作、专属性强、准确可靠的质量控制方法。方法运用薄层色谱法,考察不同展开系统、温度、湿度、厂家薄层色谱板,对方中制何首乌、陈皮、丹参进行定性鉴别。结果确定制何首乌、陈皮、丹参的展开系统分别为二氯甲烷∶乙酸乙酯(18∶0.8),乙酸乙酯∶甲酸∶水(12∶2∶3),三氯甲烷∶丙酮∶甲酸(5∶2∶0.4),阴性无干扰。结论建立了一种重复性好、专属性强、能有效提高晕宁颗粒质量标准的方法。

Objective To carry out an experimental study to improve and promote the specification of vertigocalming granules,a hospital preparation,and establish an operable,specific,accurate and reliable quality control method.Methods Thin-layer chromatography(TLC)was applied to investigate different development systems,temperatures,humidity and manufacturers of TLC plates,and qualitatively identify Polygoni Multiflori Radix Praeparata,tangerine peel and Salvia miltiorrhiza in the formula.Results The development systems to identify Polygoni Multiflori Radix Praeparata,tangerine peel and Salvia miltiorrhiza were determined as dichloromethane∶ethyl acetate(18∶0.8);ethyl acetate∶formic acid∶water(12∶2∶3)chloroform∶acetone∶formic acid(5∶2∶0.4).The results were negative without interference.Conclusion A method with good repeatability and specificity is established,which can effectively improve the specification of vertigo-calming granules.
