Abstract

The invention relates to a detection method of common goldenrop particles. The detection method of the common goldenrop particles comprises the following steps: preparation of a mixed reference substance solution: taking baicalin, baicalein, wogonin, wogonoside, ammonium glycyrrhizinate, saikoside b2 and saikoside b1 reference substances, adding a solvent for dilution to as the mixed reference substance solution and preparing a reference medicinal material solution; preparation of a test solution: taking common goldenrop particles, adding an extraction solvent for dissolving, filtering, and taking a subsequent filtrate as the test solution; and respectively injecting the mixed reference substance solution, the reference medicinal material solution and the test solution into a high performance liquid chromatograph for determination. According to the method, 15 components of 5 medicinal materials of the common goldenrop particles and 2 components of 2 medicinal materials can be subjected to qualitative treatment and quantitative treatment at the same time, the operation is simple and convenient, the repeatability is high, and the chromatographic peak pattern is good.

Description

technical field [0001] The invention relates to the field of quality control of traditional Chinese medicines, in particular to a detection method for Xiaobupleurum granules. Background technique [0002] The Xiaobupleurum granule of the present invention is a traditional Chinese medicine granule made from the traditional Chinese medicine Bupleurum Radix, Scutellaria Baicalensis, Licorice Root, Codonopsis Codonopsis, Ginger Pinellia, and Jujube. Evil criminal Shaoyang syndrome. Xiaochaihu granules have made important contributions to the prevention and treatment of SARS, influenza A, dengue fever, and new coronary pneumonia in recent years, and have been recognized by many doctors and patients. They have a good reputation and broad market prospects. [0003] In the current Pharmacopoeia standards, the thin-layer identification of Xiaochaihu granules is used to characterize baicalin, licorice and Bupleuri, respectively, and the content determination index is baicalin, which ...
