| Abstract: | The method of discriminant classification of Wuyi yan tea based on multiple chemical fingerprint by conjoining two HPLC chromatograms was studied. The results showed that samples from two raw material cultivars or from two districts could be distinguished effectively by using those discriminant method obtained from the investigation. The recognition accuracy for the training sample set was 100%, cross-validating was above 97% and the recognition accuracy for the testing sample set was about 85%. Those resul... |
