Abstract

The invention provides a ginseng extract reference substance for simultaneously detecting compounds in a ginseng medicinal material, a ginseng extract and a ginseng preparation and a preparation method thereof. The ginseng extract reference substance is white-yellow dry powder, wherein the content of total saponins of panax ginseng is not less than 50 percent; and the total content of ginsenosideRb1, ginsenoside Re and ginsenoside Rg1 is not less than 20 percent. The ginseng extract reference substance can be applied to quality control of ginseng medicinal materials and ginseng prescriptionsand qualitative and quantitative analysis and determination of effective compounds.

Description

technical field [0001] The invention belongs to the field of chemistry, and in particular relates to a ginseng extract reference substance and its application. Background technique [0002] Drug inspection is an important means to verify the quality of drugs. With the widespread use of instrumental analysis, more and more drug reference materials are used. In drug inspection work, reference substances are often used as a special reference for checking the quality of drugs, and as a comparison standard for determining the authenticity of drugs. Reference substances play a very important role in drug testing. [0003] In the current standard of traditional Chinese medicine, the quality control mode of a single component is difficult to reflect the quality of traditional Chinese medicine, and the method of comprehensive quality control using multiple components or characteristic chromatographic peaks has attracted more and more attention. However, the shortage of commercial r...
