Comprehensive Evaluation of Quality of Different Polygala tenuifolia Resources Based on Principal Component Analysis and Membership Function Method
摘要
Abstract
To establish a comprehensive method for evaluating the quality of various Polygala tenuifolia resources,14 4-year-old Polygala tenuifolia breeding materials from the germplasm resource nursery of traditional Chinese medicine in Shanxi province were studied.The agronomic traits and index components were determined.Several analytical methods including coefficient of variation analysis,correlation analysis,cluster analysis,principal component analysis,multiple linear regression analysis and membership function analysis were employed to comprehensively assess the quality of Polygala tenuifolia resources.The results showed that there were significant differences in the agronomic traits of above-ground parts and index component content of Polygala tenuifolia,with the average coefficient of variation of 15.81%and 4.24%,respectively.Correlation analysis showed that there was a strong correlation among the traits,with 44 pairs of traits showing a extremely significant correlation(P<0.01)and 17 pairs of traits showing significant correlation(P<0.05).Cluster analysis showed that polygalaxanthone Ⅲ was in the same group as the stem coarseness,the distance between saponin and root weight was the closest,and the distance between 3,6'-disinosinoylsucrose and leaf density,root branches was the closest.Through principal component analysis,all the indicators could be simplified into 7 principal components,and their cumulative contribution rate was 87.611%,which contained most of the information of Polygala tenuifolia quality index.13 key indexes were obtained using the principal component comprehensive evaluation function and multiple linear regression analysis method,which were core weight,leaf length,root thickness,phloem thickness,fine leaf saponin,leaf width,flower color,stem color development,flower density,growth habit,root branch,stem branch and stem diameter.The membership function analysis and ranking of 14 Polygala tenuifolia materials were carried out by using the key indicators,and the analysis results were consistent with the results of the principal component comprehensive evaluation function.5 core germplasms with good comprehensive performance were selected from 14 Polygala tenuifolia resources,which provided an important reference for polygala tenuifolia breeding.关键词
