Abstract:
Objective To set up a new method for fast determining and identifying Xintong Oral Liquid by acousto-optic tunable filter-near infrared(AOTF-NIR)spectroscopy.Methods Identifying method by NIR spectroscopy combined with principal component analysis(PCA),and determining model of qualitative and quantitative analyses based on PLS1 algorithm.Results The XT-C identifying model could be used to identify Xintong Oral Liquid,the determining model of qualitative and quantitative analyses with better accuracy,RMSEP of the models for puerarin was 0.137 1,the determination coefficients was R2=0.984 5.The correlation coefficient of the true value and predication value from validation was r2=0.996 4.The average recovery of the predication set was 101.9%.RSD for precision was 1.98%,RSD for stability was 1.57%.Conclusion The method is a quick and simple assay technique with low cost,which is able to be used in the qualitative and quantitive analyses on Xintong Oral Liquid.
