Detection method of polystictus versicolor and preparation containing polystictus versicolor

The invention discloses a detection method of polystictus versicolor and a preparation containing polystictus versicolor. According to the method, monosaccharide fragments obtained after polysaccharides of polystictus versicolor and the preparation containing polystictus versicolor are hydrolyzed are detected by adopting ultra performance liquid chromatography or high performance liquid chromatography while mannitose, glucose, galactose, fucose and other monosaccharide fragments are taken as evaluating indicators, and a quality control and evaluation method for measuring characteristic spectra and content of the monosaccharide fragments is established. The method can be used for quality control and evaluation of a polystictus versicolor crude drug and a preparation containing the polystictus versicolor crude drug, a polystictus versicolor extract or a polystictus versicolor effective part. The method is used for evaluating the quality of the polystictus versicolor crude drug and the preparation by controlling the monosaccharide fragments obtained after polysaccharide of the polystictus versicolor and the preparation containing polystictus versicolor are hydrolyzed. The method is strong in specificity, high in accuracy, easy and simple to operate, easy to control and higher in practical value, and can be used for effectively controlling the product quality.
