To establish a rapid analytical method for Loganin in Qiju Dihuang Pills (condensed) by Near-infrared Diffuse Reflectance Technique. Collecting NIR spectra Spectroscopy, the partial least square calibration model was built. The correlation coefficients (R 2 ) and root-mean-square error of cross-validation (RMSECV) were 0.99764 0.09340, respectively. In external validation,coefficients determination (r between NIRS HPLC values 0.97348,the prediction (RMSEP) 0.08491. results showed that rapid, accurate, could be applied to fast (condensed).
