Origin Identification of Citri Reticulatae Pericarpium Based on Miner-al Element Content Combined with Machine Learning
摘要
Abstract
The contents of mineral elements in 255 batches of Citri Reticulatae Pericarpium from Xin-hui and Guangxi were determined by inductively coupled plasma mass spectrometry.Orthogonal par-tial least squares discriminant analysis(OPLS-DA)was used to study the different elements in Citri Reticulatae Pericarpium from different producing areas.Four preprocessing methods,such as Z-score normalization,Min-Max normalization,mean normaliztion,and Max abs scaler,are used to establish a discriminant model by combining random forest(RF),decision tree(DT),support vector machine(SVM),and gradient boosting(GB)method.The results showed that among the 41 mineral elements,Na,Sn,Y,Ba,Er,Ho,Yb,Dy,Ni,Li,Gd,Tb,Sm,Nd,Rb were the main difference elements between Citri Reticulatae Pericarpium from Xinhui and Guangxi.Among the four machine learning models,the SVM model has the best prediction results.By SVM model,the accu-racy of the training group and test group under the three processing methods of Z-score normalization,Min-Max normalization,and mean normalization was the same,which was 100%and 96%,respec-tively,and the F1 value of 0.96.These result reflected the high accuracy of this method.Based on mineral element content combined with machine learning,this study established a high accuracy and reliability method for the origin identification of Citri Reticulatae Pericarpium,which provided techni-cal support for quality control of Citri Reticulatae Pericarpium and provided the basis for the origin traceability discrimination of traditional Chinese medicinal herbs.关键词
