Abstract

The invention belongs to the field of analysis of traditional Chinese medicine preparations, and particularly discloses a method for establishing a UPLC fingerprint spectrum of Xintong granules. The method comprises the steps of preparation of a test solution, determination of UPLC chromatographic conditions and preparation of a UPLC standard fingerprint spectrum. The invention also discloses a Xintong granule UPLC standard fingerprint spectrum obtained by the method, wherein the obtained fingerprint spectrum has 41 common peaks. According to the invention, the method is simple and convenient to operate, high in stability and good in reproducibility, the obtained spectrum has multiple characteristic peaks, the quality of the Xintong granules can be comprehensively evaluated and controlled by comparing the characteristic peaks with common peaks in a standard fingerprint spectrum, the stability of the product quality is facilitated, the uniformity and the stability of the internal quality of the Xintong granules are ensured, and the safety and the effectiveness of clinical medication are improved.

Description

technical field [0001] The invention belongs to the field of traditional Chinese medicine preparation analysis, and in particular relates to a method for establishing a UPLC fingerprint of Xintong granules, a fingerprint and application thereof. Background technique [0002] Xintong Granules are included in the standards issued by the national ministries. It has the effect of nourishing qi and promoting blood circulation, resolving phlegm and dredging collaterals. It is used for chest pain caused by deficiency of qi and yin and obstruction of phlegm and blood stasis, such as coronary heart disease, angina pectoris, and symptoms such as heartache, chest tightness, shortness of breath, nausea, nausea, and anorexia. The clinical effect is remarkable. [0003] At present, the current inspection items for Xintong Granules in the national ministerial standard YBZ16392009-2017 mainly include the thin-layer identification of Astragalus, Polygonum multiflorum, Epimedium and Salvia m...
