摘　　要：应用偏最小二乘法结合近红外光谱法（NIRS—PLS）对吡嗪酰胺片中吡嗪酰胺的含量进行了非破坏性定量分析。采用近红外一阶导数800—1200nm光谱区间建立了吡嗪酰胺片中吡嗪酰胺的含量定量分析模型，校正集预测值与真实值的相关系数（R）达到0．9989，预测均方根误差（RMSEP）为0．563，表明所建模型准确可靠，预测准确度高，NIRS-PLS方便快捷，可作为药品分析的一种常规方法。Near infrared diffuse reflectance spectroscopy with partial least square fitting （NIRS-PLS） was applied for nondestructive quantification of the content of Pyrazinamide in Pyrazinamide tablets. A mathematical calibration model of NIRS was proposed using the first derivative spectrum in the wavelength range from 800 to 1200 nm. For this model, the regression coefficient （R） between predicted values and actual values in calibration set is as high as 0.9989 and the root mean-square error of prediction （RMSEP） is 0. 563. Results show that this model is reliable with high prediction accuracy and is convenient for use, that can be used as general means in pharmaceutical analysis.
