Abstract

The present invention relates to a method for detecting active ingredients of a traditional Chinese medicine, and in particular relates to a method for detecting oligosaccharide component content in a compound salvia miltiorrhiza bge extract. The method comprises the following steps: (1) preparation of a reference substance solution, to be more specific, weighing fructose, glucose, sucrose, raffinose and Gal-Gal-Glu-Fru tetrasaccharide reference substances, adding water to prepare the mixed reference substance solution; (2) preparation of a to-be-tested substance solution, to be more specific, taking the compound salvia miltiorrhiza bge extract, adding water for dissolving, loading onto a solid phase extraction column, washing with water, collecting a sample loading solution and a washing solution, and adding water to prepare the to-be-tested substance solution; and (3) determination, to be more specific, sucking the mixed reference substance solution and the to-be-tested substance solution, injecting into an evaporative light scattering high performance liquid chromatography with to obtain a chromatogram map, and calculating the oligosaccharide component content in a to-be-tested substance according to the chromatogram map.

Description

Technical field: [0001] The invention relates to a method for detecting effective components of traditional Chinese medicine, in particular to a method for determining the content of oligosaccharide components in compound salvia miltiorrhiza extract. Background technique: [0002] Compound Danshen preparations are cardiovascular drugs prepared from Danshen, Panax notoginseng and borneol. Currently, there are Compound Danshen Capsules, Compound Danshen Tablets and Compound Danshen Dropping Pills on the market. In particular, compound Danshen dripping pills are widely used in the prevention, treatment and first aid of coronary heart disease and angina pectoris. Now it has become one of the leading brands in the domestic cardiovascular market. [0003] Compound Danshen extract is the extract of Danshen and Panax notoginseng. It is the intermediate of compound Danshen preparation. There are many extraction methods. The main active ingredients include protocatechualdehyde, notog...
