Quality detection method for substance reference of QingNing powder

The invention discloses a substance-based quality detection method for QingNing powder, and belongs to the technical field of quality detection of traditional Chinese medicines. The quality detection of the substance reference of the QingNing powder is realized by preparing the substance reference of the QingNing powder, identifying by adopting a thin-layer chromatography and determining the contents of mulberroside A, pachymic acid A, geniposidic acid, verbascoside and liquiritin by adopting a liquid chromatography. The quality of the substance reference of the classical famous prescription Qingning powder is evaluated through multiple detection methods, a solid foundation can be laid for stable product quality, and effective control over the quality of the substance reference of the classical famous prescription Qingning powder is achieved. 本发明公开了一种清宁散物质基准的质量检测方法，属于中药质量检测技术领域。通过制备清宁散物质基准，采用薄层色谱法进行鉴别，采用液相色谱法对桑皮苷A、茯苓新酸A、京尼平苷酸、毛蕊花糖苷和甘草苷进行含量测定，实现对清宁散物质基准的质量检测。通过多种检测方法来评定经典名方清宁散物质基准的质量，能够为产品的质量稳定奠定坚实的基础，实现经典名方清宁
