摘　　要：目的利用近红外光谱(NIR)技术建立舒胸片的快速定性和定量的分析方法。方法以舒胸片为对象,利用光纤探头采集样品的近红外光谱,通过一致性指数(CI)值和CI限度比较法建立一致性检验模型;通过在特征谱段选择合适的相关系数(r)值为阈值建立相关系数模型;通过偏最小二乘法(PLS)建立测定舒胸片中三七指标成分含量的定量模型。结果建立的一致性检验模型和特征谱段相关系数模型均可快速鉴别并准确区分舒胸片(李时珍医药集团有限公司)与其他生产厂家的同类产品,验证样品的CI值均>7.0,r值均<97%;建立的定量模型相关系数(r2)为0.973 5,交叉验证均方根偏差(RMSECV)为0.057 2,外部验证均方根偏差(RMSEP)为0.062 2。结论方法快速、简便、准确,可用于舒胸片的快速定性和定量分析。Objective To establish the rapid qualitative and quantitative analysis method for Shuxiong Tablets by Near-infrared spectra（ NIR）.Methods NIR spectrum of Shuxiong Tablets were measured by a fiber optic probe. Conformity test model was performed by comparing consistency index（ CI） value and CI limit.Characteristic spectral correlation coefficient model was established by choosing the characteristic spectral section and setting appropriate threshold value（ r）.Quantitative model for predicting the content of index component of notoginseng radix et rhizome in Shuxiong Tablets was established using partial least squares（ PLS） algorithm.Results Conformity test model and characteristic spectral correlation coefficient model can accurately distinguish Shuxiong Tablets（ manufactured by Li Shizhen Pharmaceutical Group Co.,Ltd.）from similar products of other manufacturers.The CI value of the validation samples were beyond 7.0,the threshold value（ r）were less than 97%.The correlation coefficient（ r2） of quantitative model was 0.973 5,the root mean square error of cross validation（ RMSECV） was 0.057 2,the root mean square error of prediction（ RMSEP） was 0.062 2.Conclusion The methods were simple and rapid,which can be used for rapid qualitative and quantitative analysis of Shuxiong Tablets.
