Multi-source information fusion strategies of aerial parts in FTIR-ATR spectroscopic characterization and classification of Paris polyphylla var. yunnanensis

The rational utilization of aerial parts (stem and leaf) of Paris polyphylla var. yunnanensis (P. yunnanensis) is increasingly being studied, due to the growing scarcity of resources. In our study, the geographical origin and cultivation year classification of 662 cultivated P. yunnanensis rhizome, stem and leaf samples from Yuxi, Lijiang and Honghe cities were analyzed by Fourier transform infrared-attenuated total reflectance (FTIR-ATR)...
