Objective To analyze the differences in mineral elements in wild rice from different regions and establish a method for tracing the origin of wild rice based on mineral element fingerprint characteristics. Methods Inductively coupled plasma mass spectrometry (ICP-MS) was used to analyze the content of 24 kinds of mineral elements in 40 wild rice samples from the United States, Canada, and China. The data were subjected to variance analysis, multiple analysis, principal component analysis, and discriminant analysis to explore the feasibility of using mineral element fingerprint characteristics for tracing the origin of wild rice. Results The content of 24 kinds of elements showed significant differences among the regions. Principal component analysis extracted 3 principal components, with a cumulative variance contribution rate of 93.1%. Principal component analysis successfully distinguished wild rice from the United States and Canada. Discriminant analysis correctly identified 97.7% of the wild rice samples. Conclusion This study demonstrates the feasibility and accuracy of classifying wild rice samples from different origins.
