[Identification on Solanum lyratum by FT-IR fingerprint patterns and similarity degree of different fingerprint patterns].

OBJECTIVE: To provide a FT-IR new method to identify different habitats of Solanum lyratum. METHODS: Analyzed FT-IR patterns of Solanum lyratum from different habitats, and the similarity of different fingerprint patterns was calculated and analyzed according to the wave numbers of peaks searched. RESULTS: Obtained the different FT-IR pattern of 5 different habitats of Solanum lyraturn. CONCLUSION: This method can be used for identifications on different habitats of Solanum lyratum. The results of similarity calculation further prove the feasibility of this method.
