title: [The digital criterion of the potential information characteristics of the traditional Chinese medicine chromatographic fingerprints].
abstract: OBJECTIVE
  To exploit the characteristic digital criterion for the potential information characteristics of traditional Chinese medicine chromatographic fingerprints, the 37 parameters such as F and I were firstly proposed to disclose the potential information characteristics of traditional Chinese medicine fingerprints.
  
  
  METHODS
  The HPLC fingerprints of the Ginkgo biloba extract (GBE) , Ginkgo leaf extract and diphyridamole injection (GLEDI), Ixeris sonchifolia Hance (ISH) and Ixeris sonchifolia Hance injection (ISHI) were compared each other.
  
  
  RESULTS
  As far as the peak signal intensity, the uniform of peak signal, resolution and the fingerprint information were concerned. The GBE fingerprint was better than the GLEDI's, and the ISH fingerprint was also better than the ISHI's, then GBE fingerprint was close to the ISHI' s.
  
  
  CONCLUSIONS
  The 37 parameters such as F and I can be used to objectively, authentically and thoroughly display the potential information characteristics of the traditional Chinese medicine chromatographic fingerprints.
