RESUMO
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.
