Based on ~1H-NMR-PR to establish an identification method of Ophiopogonis japonicus from different habitats / 中草药

ABSTRACT

Objective To establish a new identification method of Ophiopogonis japonicus from different habitats.Methods Using 1H-NMR to get the all component information on O.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 the 1H-NMR spectra.Results The 1H-NMR-pattern recognition(PR) method could identify the samples of O.japonicus from different habitats successively.Conclusion The 1H-NMR-PR is an useful method for identification of O.japonicus from different habitats and could be used for the quality control of traditional Chinese medicinal materials.
