目的 建立天王补心丸（小蜜丸）的近红外一致性检验模型，为其不同厂家鉴定提供依据。方法 使用MPA型近红外光谱仪（1.5 m光纤探头）OPUS5.5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4.3时，所建模型能够将不同厂家的天王补心丸（小蜜丸）快速鉴别。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（小蜜丸）的快速分类鉴别方法。

Objective To establish a consistency test model for Tianwang Buxin Pills (little honey bolus) by near-infared spectroscopic method and to provide a basis for the identification of Tianwang Buxin Pills from different manufacturers. Methods The SPA Near-infared Spectrometer (1.5 M optical fiber probe) and OPUS5.5 software were used. The average spectra of Tianwang Buxin Pills (little honey bolus) were pretreated by the second derivative+vector normalization method and the first derivative method. Results When the CI value was 4.3, the model pretreated by the first derivative method could be used to identify various Tianwang Buxin Pills (little honey bolus) from different manufacturers quickly. Conclusion This approach is convenient, rapid, and non-destructive, and can classify and identify the different Tianwang Buxin Pills (little honey bolus) from different manufacturers rapidly and nondestructively.
