摘要
使用光纤法采集替米沙坦片(40 mg)的近红外光谱,利用一致性指数(CI)值和一致性指数限度比较法,且结合偏最小二乘回归方法(PLS)建立一致性检验模型并进行定量分析。研究发现,所建立的一致性检验模型能迅速区分替米沙坦片(40 mg)与其他规格的同类产品,所建立的定量分析模型相关系数(r^(2))和外部验证均方根误差(RMSEP)分别为0.9659和0.18。结果表明该方法可用于替米沙坦片的快速定性和定量分析且方便快捷。
The telmisartan tablets(40 mg)were determined by optic fiber method.The consistency index(CI)and consistency index limit comparison method were used to establish the conformity test model,and telmisartan tablets were quantitatively analyzed by partial least squares regression(PLS)algorithm.It was found that the conformity test model can quickly distinguish telmisartan tablets(40 mg)from similar products of other specifications.The correlation coefficient(r^(2))of quantitative model and the root mean square error of external validation(RMSEP)were 0.9659 and 0.18.The results indicated that the method can be used for the qualitative and quantitative analysis of telmisartan tablets,which was convenient and rapid.
