ABSTRACT
OBJECTIVE:
To establish a method for the rapid identification of Sanjiu weitai granule and quantitative analysis of moisture.METHODS:
Near-infrared (NIR) spectroscopy was adopted. 38 batches of Sanjiu weitai granule were collected,NIR spectrum was determined by integrating sphere diffuse-reflectance. Conformity test model was performed by comparing consistency index(CI)value and CI limit,and quantitative model of moisture was established using partial least squares(PLS)algorithm. RE-SULTSWhen CI value was less than 6,the established model can accurately distinguish Sanjiu weitai granule,the model was proven feasible;the correlation coefficient (r2) of quantitative model was 97.44,the root mean square error of cross validation (RMSECV) was 0.453,the root mean square error of prediction (RMSEP) was 0.748.CONCLUSIONS:
The method is simple and rapid without destroying,which can be applied to fast screening of Sanjiu weitai granule in site and fast determination of mois-ture content.
