Fingerprint Infrared Spectrum on Rose Oral Liquid and Its Chemical Pattern Recognition
Objective: To establish a system on the quality assessment of Rose oral liquid on the combination of chemical pattern recognition. Method: Selecting the infrared spectrograms of 11 batches of Rose oral liquid and 4 kinds of counterfeit to analysis
the primary peaks were deciphered
obtained the fingerprint infrared spectrum
Moreover
according to transmittance of the different characteristic absorption peaks
the similarity was calculated
the consistency of the infrared spectrograms of 11 batches of Rose oral liquid and 4 kinds of counterfeit was investigated by similarity. The fingerprints were obtained and were handled by hierarchical clustering analysis and principal component analysis. Result: The results showed that the infrared spectrograms of 11 batches of Rose oral liquid for were not only in good agreement
but also Rose oral liquid and counterfeit could completely be distinguished by similarity analysis and chemical pattern recognition
and the result of similarity was the same as cluster analysis or principal component analysis
the two methods of chemometrics showed good correlation. Conclusion: The method was convenient for differentiation of counterfeit and applicable to quality evaluation of Rose oral liquid.
