摘要:

运用X射线荧光光谱、近红外光谱法区分道地与非道地附子。搜集道地产地附子和其他产地附子,通过对附子进行处理后,采用Axios型X射线荧光光谱仪和Antaris Ⅱ傅里叶变换近红外光谱仪对样品进行扫描。发现Na和Mg元素含量的差异可以作为道地附子的特征标识,利用马氏距离建立三维空间模型,能将江油附子和其他产区附子区分,具有很好的预测性能。因此,利用X射线荧光光谱和近红外光谱技术能快速、有效实现对道地江油附子的鉴别。

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
