title: [Identification on Spora Lygodii by X-ray diffraction fingerprint spectra method].
abstract: OBJECTIVE
  To set up a new identification and analysis method of Spora Lygodii.
  
  
  METHODS
  To get the extracts of Spora Lygodii using methanol, chloroform and petroleum ether as solvent and the extracts were identified, analyzed by X-ray diffraction Fourier fingerprint spectra.
  
  
  RESULTS
  Experiments and analysis were carried out on three samples. The standard X-ray diffraction Fourier fingerprint spectra and characteristic diffraction peaks were obtained. There were some differences among the spectra of the extracts, but the characteristic diffraction peaks were obvious.
  
  
  CONCLUSIONS
  The experimental result indicated that X-ray diffraction Fourier fingerprint spectra can be used to identify and analyze the Chinese traditional herb Lygodium japonicum (Thunb.) Sw.
