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.
