目的:探索6种含硫酸盐的矿物类中药及石膏、白矾炮制品的拉曼光谱快速鉴别方法。方法:应用拉曼光谱分技术对6种含硫酸盐类矿物药及石膏炮制品进行分析,结合OPUS软件对各类矿物药的特征谱线进行了归纳和分析。结果:OPUS软件将拉曼光谱信息进行归纳,其聚类分析结果不仅将6类含硫酸盐类矿物药区分开,同时也把不同炮制程度的炮制品和生品区分开来。结论:拉曼光谱不仅可以对硫酸盐类矿物药进行快速准确的分类鉴别,同时也反映了硫酸盐类矿物药炮制前后、炮制程度的差异。
Objective: To explore the rapid identification of six kinds of sulphate-containing minerals Chinese medicine and gypsum and white alum products by Raman spectroscopy. Methods: Six kinds of sulfate-containing mineral medicine and gypsum processed products were analyzed by Raman spectroscopy. Combined with OPUS software, the characteristic lines of various mineral drugs were summarized and analyzed. Results: The OPUS software summarized the Raman spectrum information. The clustering results not only distinguished the six types of sulfate-containing mineral drugs, but also distinguished processed products and raw products with different processing levels. Conclusions: Raman spectroscopy not only can quickly and accurately classify sulfate mineral drugs, but also reflect the differences in the degree of processing before and after the sulfate mineral drugs are processed.
