分别采用近红外光谱(NIR)法、高效液相色谱(HPLC)法及紫外光谱(UV)法测定不同厂家的46批灯盏花素片,以相关性分析和回归分析法对测定结果进行比较分析。结果显示,3个方法的测定值有一定差异,但相关性较好。NIR法准确、快速、无损,可用于药品的现场快速分析。 The 46 batches of breviscapine tablets from different manufacturers were determined by NIR, HPLC and UV spectrophotometry. The correlation analysis and regression analysis were used to analyze the results . The results show that the three methods have some differences between the measured values, but the correlation is good. The NIR method is accurate, rapid and non-destructive and can be used in the field of pharmaceuticals for rapid analysis.
