Abstract:
OBJECTIVE:To establish a method of quick identification of Fufang yuxingcao tablel(manufactured by A). METH-ODS:NIRDRS was adopted,the near-infrared diffuse reflectance spectrum were recorded by a fiber optic probe,and the conformi-ty test model was established through the consistency index (CI) value and the CI limit comparison method. The spectral range of 9 002-7 497.8 cm-1 ,6 903.8-5 596.4 cm-1 and 5 002.4-4 246.4 cm-1 was selected as the characteristic spectral band ,the spectra were preprocessed by first derivation and vector normalization with 17 smoothing points , and 7.0 was set as the CI value;the characteristic spectrum correlation coefficient model was established through the correlation coefficient method ,the spectral range of 6 200-5 500 cm-1,5 000-4 700 cm-1 was selected as the characteristic spectral band,the spectra were preprocessed by first deri-vation with 17 smoothing points,and 97% was set as the threshold. RESULTS:The above established models can rapidly identify and accurately distinguish Fufang yuxingcao tablet(manufactured by A)from similar products of other manufacturers,the CI value of the validation samples was beyond 7.0,the correlation coefficient(r)were less than 97% compared with the reference sample. CONCLUSIONS:The method is simple and rapid,and can be used for fast screening of Fufang yuxingcao tablet.
