目的建立一种基于氢核磁共振-模式识别的不同产地麦冬鉴别新方法.方法以¹H-NMR技术测定样品的全成分信息,并转化成数据矩阵,采用模式识别法中的主成分分析(PCA)、偏最小二乘法-判别分析(PLS-DA)以及聚类分析(HCA)进行识别分析.结果氢核磁共振-模式识别法能有效地鉴别不同产地的麦冬样本.结论氢核磁共振-模式识别法是一种有效的药材分类鉴别方法,可作为药材质量控制的手段之一.

Objective To establish a new identification method ofOphiopogonis japonicusfrom different habitats.Methods Using¹ H-NMR to get the all component information onO.japonicus,and using pattern recognitions,such as principal component analysis (PCA),partial least squares-discriiminate analysis(PLS-DA),and hierarchical cluster analysis(HCA)to analyze the data from the¹H-NMR spectra.Results The¹H-NMR-pattern recognition(PR)method could identify the samples ofO.japonicusfrom different habitats successively.Conclusion The¹H-NMR-PR is an useful method for identification ofO.japonicusfrom different habitats and could be used for the quality control of traditional Chinese medicinal materials.
