Abstract

The invention belongs to the field of monosaccharide component analysis, and in particular relates to a method for detecting monosaccharide components in rainbow conk glycopeptide. The method comprises the following steps of: carrying out a test on HPLC (High Performance Liquid Chromatography) chromatographic condition and systematic compatibility; subsequently respectively absorbing a mixed reference solution and a test solution to be injected into the HPLC chromatographic instrument so as to obtain a chromatogram, wherein the reference solution is a 1phenyl-3-methyl-5-pyrazolone derivative solution of D-glucose, D-mannose, D-xylose, L-xylose, D-galactose, D-arabinose, D-hydrochloric acid glucosamine and L-rhamnose reference solutions; and the test solution is a 1-phenyl-3-methyl-5-pyrazolone derivative solution of a rainbow conk glycopeptide acid hydrolysis product. Polysaccharide peptide products such as rainbow conk glycopeptide, rainbow conk intracellular glycopeptide, rainbow conk extracellular glycopeptides and coriolus versicolor polysaccharide are distinguished by detecting the mole ratio of eight monosaccharide ingredients in a test sample, so that the quality and the curative effect of the rainbow conk glycopeptide are ensured.

Description

technical field [0001] The invention belongs to the field of analysis of polysaccharide components, and in particular relates to a method for detecting monosaccharide components in versicolor glycopeptides. Background technique [0002] Yunzhi glycopeptide is a Chinese patent medicine extracted from the liquid fermented mycelia of the basidiomycete Yunzhi Cov-1 strain. Its active ingredient is binding proteoglycan. Tumor, anti-oxidation, lowering blood fat, promoting the recovery of damaged liver cells, etc., for esophageal cancer, gastric cancer and primary lung cancer patients with deficiency of both qi and yin and deficiency of heart and spleen caused by radiotherapy and chemotherapy. Yunzhi glycopeptide is a kind of natural macromolecular organic matter with complex and diverse structures. The national standard WS3-228(Z-047)-2003(Z) of Yunzhi Glycopeptides records the main quality control indicators such as the determination of polysaccharide content and protein conten...
