[Application of HATR-FTIR spectroscopy combined with cluster analysis to identification of Cuscuta chinensis lam and its unofficial varieties].
Horizontal attenuated total reflectance Fourier transform infrared spectroscopy was used to identify Cuscuta chinensis lam. samples directly and their chemical differences were compared. In addition to FTIRS/cluster analysis, the kindredship between the different varieties of official and unofficial Cuscuta chinensis lam was studied. As shown by the results of cluster analysis, the four samples mentioned above were separated to three groups. The proposed method can be effectively applied to analyse the qualitify of Cuscuta chinensis lam.
