RESUMEN
OBJECTIVE: To provide an X-ray diffraction (XRD) method for identifying different medicinal parts of Solanum lyratum. METHODS: Analyzed X-ray diffraction Fourier patterns of different parts of Solanum lyratum, and the similarity degree of different fingerprint was calculated and analyzed according to the position (2 theta value)of peaks searched. RESULTS: Different X-ray diffraction Fourier patterns of different medicinal parts of Solanum lyratum were obtained. CONCLUSION: This method can be used for identifying different medicinal parts of Solanum lyratum. The results of similarity calculation further proves the feasibility of this 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.
