[Identification on Spora Lygodii by X-ray diffraction fingerprint spectra method].

Objective: To set up a new identification and analysis method of Spora Lygodii.Method: 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.Conclusion: 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.
