| description | The invention provides a polysaccharide active component information-based astragalus membranaceus quality grade evaluation method, which comprises the following steps of: acquiring sample information by using nuclear magnetic resonance hydrogen spectrum to obtain a data matrix, extracting characteristic variables by using a step-by-step discriminant analysis method, establishing different Fisher discriminant functions, and evaluating the quality grade of astragalus membranaceus according to the different Fisher discriminant functions. And completing the discrimination of astragalus mongolicus and astragalus membranacus of different original samples of the traditional Chinese medicine astragalus mongholicus, the discrimination of samples of different planting modes and the discrimination of samples of different producing areas. The discrimination accuracy can reach 100%, and a foundation is laid for the overall quality control and evaluation of astragalus membranaceus.
