【摘要】 武夷岩茶属于闽北乌龙茶,是福建省的特有茶类,其也是我国传统名茶中的精品,尤其以武夷中心地带所产的正岩茶品质最佳。本研究利用HPLC色谱数据的多元信息融合,进行了武夷岩茶的分类识别研究,建立了武夷岩茶不同原料品种、不同产地区域的分类判别模型,模型对训练集样本的判别准确率达到100%,交叉验证准确率达到97%以上,对外部验证集样本的判别准确率达到85%左右。本研究初步证明了利用多元化学指纹图谱判别分析方法对武夷岩茶进行分类识别的可行性。更多还原

【Abstract】 Wuyi Yan tea was one type of Oolong tea which was produced only in north of Fujian province. It was a famous tea in China and the quality of Zheng Yan tea which was manufactured of tea leaves planted in the centre area of Wuyi mountain was best in Wuyi Yan tea. The method of discriminanting classification of Wuyi yan Tea was studied based on multiple chemical fingerprint through conjoining two HPLC chromatograms. The resultshowed that samples from two raw material cultivar or from two region 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 test sample set was about 85%. Those result revealed that it was possible to distinguish or verify Wuyi Yan tea by combining the techniques of multiple chemical fingerprint and discriminant classification.更多还原
