ABSTRACT
OBJECTIVE:To apply AOTF-near infrared spectroscopy for quick identification of Shuanghuanglian oral liquid and Yinhuang oral liquid.METHODS:Yinhuang oral liquid and Shuanghuanglian oral liquid samples of different batches from different manufacturers were collected for collection of their near infrared spectra.The qualitative analysis models of the two kinds of oral liquid were established respectively using principal component analysis.Meanwhile,the established models were used to analyze and validate each other.RESULTS:The established qualitative analysis models of Shuanghuanglian oral liquid and Yinhuang oral liquid could be applied to validate and identify each other correctly.CONCLUSION:The method was proved to be a simple,rapid new analytical technique with low cost,and it can be used for a quick identification of Shuangh-uanglian oral liquid and Yinhuang oral liquid.
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.
ABSTRACT
AIM:A new method to rapidly non-destructive quality control Compound Danshen Tablet was developed by portable acousto-optic tunable filter (AOTF)-near infrared (NIR) spectroscopy. METHODS:A portable AOTF-NIR spectrometer was used to test 215 different batches of Compound Danshen Tablet collected from fifty-six pharmaceutical factories. The samples were analyzed by the Unscrambler program using principal component analysis(PCA). Quantitative analytical models invoking the partial least squares (PLS) algorithm simultaneously predicted the contents of four major constituents in Compound Danshen Tablet:salvianolic acid B,tanshinoneⅡA,water extract and alcohol extract. RESULTS:The qualitative analysis models accurately identified the differences between Compound Danshen Tablet and other reference substances. The results of external validation showed by the significant t-test that no significant difference between predictive and the chemical value,RSD was equal to 0. 990 9,0. 991 3,0. 964 0 and 1. 73% ,2. 08% ,3. 32% ,1. 32% ,respectively. CONCLUSION:The method of rapid non-destructive analyzing Compound Danshen Tablet is explored.
ABSTRACT
AIM:To establish a new method of rapid analysis of puerarin in Xintong Oral Liquid by acousto-optic tunable filter-nearinfrared spectroscopy. METHODS: HPLC was used as a reference method to determine puerarin content in Xintong Oral Liquid. Calibration model based on partial least squares(PLS1) algorithm was developed to correlate the spectra and the corresponding values determined by the reference methods. RESULTS: The root mean square error of prediction(RMSEP) of the model for puerarin was 0.137 1. The determination coefficient was R～2=0.984 5. The correlation coefficient of the true value and predication value from validation was r～2=0.996 4. CONCLUSION: The method is a quick, simple and low cost assay and able to be used in quantitative analysis of Xintong Oral Liquid.
ABSTRACT
AIM: To establish a new method for quick identifying Shuanghuanglian Oral Liquid(Flos Lonicerae japonicae,Radix Scutella riae,Fructus Forsythiae) by AOTF-Near infrared spectroscopy. METHODS: Near infrared spectroscopy combined with principal component analysis. RESULTS: The model SHL-C of Shuanghuanglian Oral Liquid could distinguish Shuanghuanglian Oral Liquid from Yinhuang Oral Liquid and other 9 kinds of these(oral) liquids. CONCLUSION: The method is quick,simple and low cost assay technique and can be used to identification of Shnanghuanglian Oral Liquid.
