近红外光谱法快速鉴别不同厂家的天王补心丸（大蜜丸）

目的：建立天王补心丸（大蜜丸）的近红外一致性检验模型,为其不同厂家鉴定提供科学依据。方法：使用MPA型近红外光谱仪（1.5 m光纤探头）、OPUS 5.5软件,分别采用二阶导数＋矢量归一化法和一阶导数法对其平均光谱进行预处理。结果：采用一阶导数预处理方法,CI值设为4.4时,所建模型能够将不同厂家的天王补心丸（大蜜丸）快速鉴别出来。结论：此方法方便、快捷、不破坏样品,能够作为不同厂家天王补心丸（大蜜丸）的快速分类鉴别方法。

Identification of Tianwang Buxin pills (big honeyed pills)from different manufacturers by near-infared spectroscopic method

Objective： To establish a conformity test model of Tianwang Buxin pills（ big honeyed pills） by near- infared spectroscopic method,to provide basis for the identification of different manufacturers. Methods： Using the MPA near infrared spectrometer（ 1. 5 m probe） with OPUS 5. 5 software,the average near- infared spectra of Tianwang Buxin pills（ big honeyed pills） were processed with the second derivative ＋ vector normalization method and the first derivative method. Results： When the CI value was 4. 4,the model preprocessed by the first derivative method can identify different Tianwang Buxin pills（ big honeyed pills） from different manufacturers quickly. Conclusion： This approach is convenient,rapid and non- destructive,and can classify and identify different Tianwang Buxin pills（ big honeyed pills） from different manufacturers rapidly.
