摘　　要：采用近红外漫反射光谱分析技术对同仁乌鸡白凤丸进行定性和定量分析.采集了98份同仁乌鸡白凤丸和58份不同厂家乌鸡白凤丸样品的近红外漫反射光谱.采用判别分析法对同仁乌鸡白凤丸和乌鸡白凤丸进行鉴别.以70份同仁乌鸡白凤丸的近红外光谱为标准,建立相似度匹配模型,并将其用于计算其余样品的相似度.采用偏最小二乘回归法建立了同仁乌鸡白凤丸总氨基酸、芍药苷、水分含量的定量分析模型,对未知样品进行含量预测.结果判别分析模型的错判数为0.相似度匹配模型能正确区分同仁乌鸡白凤丸和乌鸡白凤丸.校正模型的相关系数分别为0.9614,0.9651,0.9910,验证集均方差分别为0.199%,0.00436%,0.386%.本方法准确可靠,操作简便,快速无损,可推广用于工业现场的原位检测.Tongren wuji Baifeng pills were analyzed qualitatively and quantitatively by near infrared spectroscopy. Near infrared diffuse reflectance spectra of 98 Tongren Wuji Baifeng pills and 58 Wuji Baifeng pills from different manufacturers were collected. Discriminant analysis was used to distinguish Tongren Wuji Baifeng pills from Wuji Baifeng pills. Similarity match model was built based on the spectra of 70 batches of Tongren Wuji Baifeng pills. By using this model, the similarity match values of other samples were calculated. Quantitative analysis models for total amino acids, paeonin and water content in Tongren Wuji Baifeng pills were developed with partial least square algorithm. No misclassified sample was detected by discriminant analysis. The similarity match model could distinguish different samples. The correlation coefficients of the calibration models were 0. 9614, 0. 9651 and 0. 9910 while the values of root mean square error of prediction were 0. 199% , 0.00436% and 0.386% , respectively. The proposed methods are accurate, fast and non-destructive, and can be applied to at-spot detection.
