experiment example 1
[0030] Experimental example 1: Study on the characteristic map of versicolor versicolor medicinal material and its preparation
[0031] Since Yunzhi polysaccharides are a large class of heteropolysaccharides with complex structures, there is still no specific quality control method to distinguish different types of polysaccharides. However, the method of the present invention is stable, has good reproducibility, strong specificity, can distinguish different types of polysaccharides, and can be used to control and evaluate the quality of versicolor versicolor medicinal material and its preparations. The test results are as follows:
[0032] 1. Preparation of reference solution
[0033] Preparation of reference solution Accurately weigh an appropriate amount of standard monosaccharide, and dissolve it in water to prepare a suitable monosaccharide standard liquid.
[0034]Derivatization amount of reference solution Take an appropriate amount of the above reference solution, ...
experiment example 2
[0068] Experimental example 2: Determination of the content of each monosaccharide in Yunzhi medicinal materials and its preparations
[0069] Since the polysaccharide content of Versicolor versicolor medicinal material and its preparations is mostly measured by spectrophotometry and titration, and glucose is used as a reference substance, this type of method has poor specificity, low accuracy, and poor quality controllability. The present invention adopts its main single method The content of sugar components controls the quality of polysaccharides in traditional Chinese medicine. The test results show that the separation effect is good under the selected conditions, and the linearity, stability, repeatability, and recovery of each monosaccharide meet the requirements of content determination. It can be used to control the quality of polysaccharides in traditional Chinese medicine, and can effectively evaluate the quality of medicinal materials and preparations containing poly...
