ABSTRACT
<p><b>OBJECTIVE</b>To establish a new method using AOTF-Near infrared spectroscopy for fast identifying Fufang Danshen tablets.</p><p><b>METHOD</b>Near-infrared spectroscopy of Fufang Danshen tablets from different factories and different bacth numbers were collected and the discriminant analysis model (FFDS-C) was established with principal component analysis. This model was applied to predict the the different samples of Fufang Danshn tablets.</p><p><b>RESULT</b>The model can be used to precisely identify Fufang Danshen tablets from other samples.</p><p><b>CONCLUSION</b>The method with low consumption is simple and quick and can be applied to the identification of the Fufang Danshen tablets.</p>

<p><b>OBJECTIVE</b>To establish a new method using AOTF-Near infrared spectroscopy (NIRS) for quick determination of tanshinone II(A) and salvianolic acid B in Fufang Danshen tablets.</p><p><b>METHOD</b>HPLC was used as a reference method to determine the contents of tanshinone II(A) and salvianolic acid B in Fu Fang Dan Shen tablets. Multivariate calibration models based on PLS1 algorithm were developed to correlate the spectra and the corresponding values determined by the reference methods.</p><p><b>RESULT</b>RMSECV (root-mean-square error of cross-validation) of the models for tanshinone II(A) and salvianolic acid B were 0.0103 and 0.1868 respectively. The correlation coefficients of the calibration models were 0.9873 and 0.9832 respectively. External validation with external validation samples proved that the relative coefficient of the predicted value and the truth value were R2 = 0.9743 and R2 = 0.9886 respectively, with measured recycle rates of 103.0% and 99.0%.</p><p><b>CONCLUSION</b>NIRS can be used in the determination of tanshinone II(A) and salvianolic acid B, which sets up the foundation of product-line control of Fuang Danshen tablets.</p>
