title: [Application of near infrared spectroscopy to identify authenticity of Polygonum multiflorum].
abstract: OBJECTIVE
  To establish a near-infrared qualitative analysis model to identify the authenticity of Polygonum multiflo- rum and distinguish processed products Polygoni Multiflori Radix.
  
  
  METHODS
  The NIR spectra were peformed on over 30 batches of P. multiflorum and Polygoni Multiflori Radix samples and the adulterants Cynanchum bungei, Pteroxygonum giraldii, Polygonum cillinerve to establish the qualitative discriminant model and the conformity test model of Polygonum multifiorum , and cluster analysis was used to analyze the samples from different origins.
  
  
  RESULTS
  The model is able to identify correctly P. multiflorum with its counterfeit, and distinguish between P. multiflorum and Polygoni multiflori Radix.
  
  
  CONCLUSIONS
  Near-infrared spectroscopy can be applied in the identification of P. multiflorum, which could be used to screen Chinese herbal medicine preliminarily.
