title: [Identification of Chinese medicine material of Fritillaria by themogravimetric/diffrential thermal analysis].
abstract: OBJECTIVE
  To provide a quick and simple method to identify different Chinese medicine material of Fritillaria.
  
  
  METHODS
  The thermograms and differential thermograms of nine Fritillaria powders were obtained by thermal analyzer.
  
  
  RESULTS
  By analyzing the thermograms of nine Fritillaria powders, we concluded that the thermal stability of nine Fritillaria powders was much different each other due to the different geography origin. The thermal stability of F. hupehensis was highest among nine Fritillaria, while F. ussurensis was the lowest. The different Fritillaria showed their own DTA spectra respectively.
  
  
  CONCLUSIONS
  According to the differences in the thermal properties of nine Fritillaria powders, the origins of Fritillaria could be easily identfied.
