Abstract

The invention relates to a method for determining fingerprint of a Shuanghuanglian oral preparation and belongs to the technical field of drug analysis. The method comprises: preparing a reference solution and a test solution and carrying out analysis detection through high performance liquid chromatography-mass spectrometry. The HPLC detection is carried out under different elution conditions sothat good separation effects are obtained. Through an external internal standard method, the test solution containing the internal standard substance is detected in the fingerprint. The relative peakarea ratio of the common peak and the internal standard peak is used as the mathematical expression of the fingerprint so that the method can reflect the absolute and relative changes of common peak contents better than the method for calculating the relative peak area of each common peak through traditional Chinese medicine ingredients.

Description

technical field [0001] The invention relates to a fingerprint determination method of Shuanghuanglian oral preparation, which belongs to the technical field of drug analysis. Background technique [0002] Shuanghuanglian prescription is simplified and tailored from Yinqiaosan ("Warm Disease Tiaodian"). It is a modern Chinese medicine compound preparation composed of Shuanghua (honeysuckle), Scutellaria baicalensis and Forsythia. The function of detoxification is a commonly used medicine for colds caused by exogenous wind-heat. Pharmacological studies have shown that it has good antibacterial, antiviral, antipyretic and anti-inflammatory effects, and is currently one of the first-choice drugs for clinical treatment of respiratory infectious diseases. The "Chinese Pharmacopoeia" has been developed from 2000 to the 2015 edition (Part One), and its oral dosage forms include oral liquid, tablet, granule and capsule, and it has been approved by the State Food and Drug Administrati...
