title: [Research on medical speciality of traditional Chinese medicines using dot-immunoblotting method based on polyclonal antibody prepared from traditional Chinese medicines with hot/cold nature].
abstract: OBJECTIVE
  To research on the substantial foundation of the medical speciality of Chinese traditional medicines from immunogenicity.
  
  
  METHODS
  Control antigen with hot nature was prepared from the mixture of the aqueous extracts of three Chinese traditional medicines with three typical hot nature of Alpinia officinarum, Cinnamomum cassia and Curculigo orchioides, while that with cold nature prepared with Rheum palmatum, Anemarrhena asphodeloides, Coptis chinensis, and polyclonal antibody was prepared by immunizing rabbit with control antigen. Dot blotting was performed between the polyclonal antibody of control antigen and the aqueous extracts of nine Chinese traditional medicines on a piece of PVDF membrane, and the blotting signals were analyzed by the software of Quantity One.
  
  
  RESULTS
  Blotting signals with hot control antigen of nine Chinese traditional medicines in descending were Zingiber officinale, Aconitum carmichaeli, Eucommia ulmoides, Fraxinus rhynchophylla, Lonicera japonica, Anemarrhena asphodeloides, Coptis chinensis, Rheum palmatum and Phellodendron chinense, which degree of similarity to control antigen in peak value were 57.33%, 43.56 %, 34.16%, 30.2%, 28.81%, 26.53%, 21.68%, 17.62% and 14.85%, respectively. Blotting signals with cold control antigen were Rheum palmatum, Anemarrhena asphodeloides, Coptis chinensis, Phellodendron chinense, Zingiber officinale, Lonicera japonica, Fraxinus rhynchophylla, Eucommia ulmoides and Aconitum carmichaeli in descending, of which degree of similarity to cold control antigen in peak value were 55.22%, 54.23%, 46.72%, 34.08%, 30.3%, 24.48%, 24.33%, 20.35% and 15.17%, respectively. Results of cluster analysis with Wistar's method showed that nine medicines were classified into two groups, one group included Phellodendron chinense, Anemarrhena asphodeloides, Coptis chinensis, Rheum palmatum, another was Zingiber officinale, Aconitum carmichaeli, Eucommia ulmoides, Fraxinus rhynchophylla, Lonicera japonica.
  
  
  CONCLUSIONS
  Blotting signals of nine medicines with control antigen regularly varied with the alteration of medicine nature. The more similarity degree of the tested medicine to control antigen was smaller, the more distance of the tested medicine to control antigen was further. Dot immunoblotting was a practical and effective new method in researching the substantial foundation of the medical speciality of Chinese traditional medicines.
