研究了近红外一阶导数光谱进行芦丁粉末药品质量控制的可能性，用多变量统计分类技术（ 系统聚类分析、逐步聚类分析、主成分分析和逐步判别分析） 从芦丁粉末药品的近红外一阶导数光谱成功地鉴别了真药、劣药和假药。
The possibility of quality control of rutin powder medicines using near-infrared first-order derivative spectra was studied using multivariate statistical classification techniques (systematic cluster analysis, stepwise cluster analysis, principal component analysis and stepwise discriminant analysis) from rutin powder medicines Near-infrared first-order derivative spectra successfully identified real, inferior, and counterfeit drugs.
