Abstract:

X-ray fluorescence spectroscopy and near-infrared spectroscopy were used to differentiate geo-herbalism of Aconitum carmichaeli. Geo-herbalism samples from different production areas and other samples were collected. After processing the samples, they were scanned using an Axios type X-ray fluorescence spectrometer and an Antaris Ⅱ Fourier-transform near-infrared spectrometer. The differences in Na and Mg element content were identified as characteristic markers for authentic samples. By using Mahalanobis distance to establish a three-dimensional spatial model, it was possible to distinguish Jiangyou samples from samples from other production areas, showing good predictive performance. Therefore, X-ray fluorescence spectrometry and near-infrared spectroscopy techniques can be used to rapidly and effectively identify authentic Jiangyou Aconitum carmichaeli.

Key words: Aconitum carmichaeli, geo-herbalism, X-ray fluorescence spectrometry, near-infrared spectroscopy
