Problems solved by technology

Cordyceps militaris polysaccharides have been tested and analyzed, and they are mainly heteropolysaccharides composed of glucose, mannose, arabinose, galactose, rhamnose, and xylose. In addition, they also contain complexes such as proteins and nucleic acids. Cordyceps militaris has been reported The molecular weight of the purified polysaccharide ranges from thousands to hundreds of thousands of Daltons. Therefore, the polysaccharide of Cordyceps militaris is a complex macromolecular compound with a variety of special and quite complex chemical structures in most cases. Mainly manifested in: the type, molecular weight and distribution of monosaccharides that make up polysaccharides, the composition of polysaccharide complexes (proteins and nucleic acids), sugar chain structures, and advanced structures are all very complex, and it is difficult to identify general polysaccharides by single chemical analysis methods and instrumental analysis methods These factors will affect the quality of polysaccharides, thereby affecting the activity of polysaccharides and the efficacy of Cordyceps militaris medicinal materials. Therefore, how to control the quality of Cordyceps militaris polysaccharides with simple, fast and accurate methods is an urgent need a problem solved
[0004] The existing single fingerprint method has the disadvantage that it is difficult to overcome, that is, it is difficult to determine whether the unknown sample conforms to the fingerprint of the standard sample, and false positive results sometimes appear

Abstract

The invention discloses a construction method of a cordyceps militaris polysaccharide multi-dimensional fingerprint spectrum, which relates to the technical field of fingerprint spectrums of traditional Chinese medicine and functional food materials as well as products of the traditional Chinese medicine and the functional food materials. The construction method comprises the steps of extracting cordyceps militaris polysaccharide from cordyceps militaris and performing ultraviolet absorption spectrum fingerprint analysis, Fourier transform infrared spectroscopy fingerprint analysis and high performance gel permeation chromatography fingerprint analysis on the extracted cordyceps militaris polysaccharide so as to obtain a multi-dimensional fingerprint spectrum of the cordyceps militaris polysaccharide including an UV standard fingerprint spectrum, an IR standard fingerprint spectrum and HPGPC standard fingerprint spectrum. The method has the advantages of simplicity, stability and sensitivity in operation, high precision, good reproducibility and the like, the quality of the cordyceps militaris polysaccharide can be controlled from the integral feature of the chromatography, and a new scientific method is provided for the quality control and true and false identification of the cordyceps militaris.

Description

technical field [0001] The invention relates to the technical field of fingerprints of traditional Chinese medicine and functional food raw materials and their products, in particular to a method for controlling the quality of polysaccharides from Cordyceps militaris by using multi-dimensional fingerprints. Background technique [0002] Cordyceps militaris ( Cordyceps militaris) Also known as Cordyceps militaris, Cordyceps militaris, and Chrysalis pupae. Cordyceps militaris is a precious traditional Chinese medicinal material in my country. The people have long studied and recognized its medicinal value. In 1518, Li Shizhen recorded in "Compendium of Materia Medica" that cicadae can cure "children with convulsions, night crying, and heart palpitations". According to the textual research of Jing Yibing and others, the "Cicada Flower" at that time included Cicada Cordyceps ( C. sobolifera ) and Cordyceps militaris ( C. militaris ) and many other Cordyceps that parasitize ...
