Abstract

The invention relates to a UPLC fingerprint spectrum construction method and detection method of Angongniuhuang Pills. The method for constructing UPLC fingerprints includes the following steps: preparation of reference substance solution: take geniposide reference substance, add solvent to dissolve, and obtain the reference substance solution; preparation of test solution: take Angong Niuhuang Pill sample, add volume concentration Extract for 70~80% methanol aqueous solution, filter, get continued filtrate, obtain described need testing solution; Fingerprint spectrum construction: inject described reference substance solution and need testing solution in the ultra-high performance liquid chromatograph respectively, Determination, the fingerprint spectrum is obtained. The construction method calibrated 25 common peaks and identified 17 chromatographic peaks within 30 minutes. The method is simple, fast, accurate and reproducible. scientific basis.

Description

technical field [0001] The invention relates to quality control of traditional Chinese medicines, in particular to a method for constructing UPLC fingerprints and a detection method for Angongniuhuang Pills. Background technique [0002] Angong Niuhuang Pill comes from "Tiaodian of Febrile Diseases" written by Wu Tang, a physician in the Qing Dynasty. The effect of detoxification, eliminating phlegm and resuscitation is widely used in the treatment of stroke, coma, ischemic hypoxic encephalopathy, hypertensive cerebral hemorrhage, etc., and the curative effect is accurate and reliable. Modern pharmacological studies have shown that Angong Niuhuang Pills have good anticonvulsant, brain injury protection, anti-inflammatory and detumescent effects, and can reduce experimental hypertension in animals. At the same time, it can also enhance the body's immune response, and can improve whole blood viscosity, plasma Viscosity, which plays a role in protecting the brain injury of isc...
