Analysis and identification of wild and cultivated Paridis Rhizoma by infrared spectroscopy

Wild and cultivated Paridis Rhizoma (PR) were analyzed and characterized systematically by integral analysis method and two dimensional correlation infrared spectroscopy, both of which have been successfully utilized in the analysis of complex mixtures. According to their infrared spectra, peaks clusters at around 1642 and 1022 cm−1 could be considered as the key factors to discriminate them. Besides, significant differences emerged in their...
