Rapid identification of the origins of Coicis Semen based on low-field NMR technique
Objective To identify the origin of 25 batches of Coicis Semen samples from five different regions.Methods Low field NMR analyzer was used to analyze the characteristic types and contents of moisture and lipids,and the data were normalized and clustered.Results In this test,the moisture and lipid contents of Coicis Semen from five different regions were not significantly different.While the origins of Coicis Semen could not be independently identified with the conventional test,they were accurately classified by low-field NMR analyzer with the success rate of 100%.All 25 samples were analyzed under 3 hours with 2 minutes for each.Conclusion Rapid and accurate identification of the origin of Chinese medicinal materials by non-traditional analytical instruments can promote the development of specialty agriculture and the rational research on the modernization of Chinese medicinal materials.
