Abstract:
ObjectiveBased on the supramolecular "imprinting template" theory， the autonomous action law of the component groups of Shentong Zhuyutang in the preparation process of medicinal materials-decoction pieces-formulas was studied to clarify the quantitative transfer law of its quality attributes. MethodUltra performance liquid chromatography（UPLC） fingerprint of Shentong Zhuyutang was established with mobile phase of 0.4% phosphoric acid aqueous solution（A）-acetonitrile（B） for gradient elution（0-2.5 min， 100%A； 2.5-6 min， 100%-96%A； 6-15 min， 96%-92%A； 15-25 min， 92%-88%A； 25-35 min， 88%-75%A； 35-50 min， 75%-65%A； 50-60 min， 65%-50%A； 60-65 min， 50%-30%A； 65-70 min， 100%A） and detection wavelength of 235 nm， and the total statistical moments， information entropy and primary feeding amount of fingerprint of medicinal materials， decoction pieces and benchmark samples were calculated. Dry extract rate of the benchmark samples， the transfer rates and the addition parameters of medicinal materials-decoction pieces-formulas were calculated. ResultSimilarities of the total statistical moments of UPLC fingerprint of 15 batches of medicinal materials and decoction pieces were>0.89， the relative standard deviations（RSDs） of information entropy of UPLC fingerprint of 12 medicinal materials and decoction pieces were<10%. RSDs of total first-order moment（MCRTT） and information entropy of Shentong Zhuyutang（medicinal materials） were 5.5% and 2.3%， while the RSDs of MCRTT and information entropy of Shentong Zhuyutang（decoction pieces） were 4.8% and 2.6%， respectively. The dry extract rate of 45 batches of Shentong Zhuyutang was 17.2%-20.2%. The transfer rate of medicinal materials to decoction pieces was within the range of data fluctuation， which was 70%-130% of the average value. The overall transfer rates of medicinal materials to decoction pieces and decoction pieces to benchmark samples were 101.8% and 83.0%， respectively. ConclusionThe quality properties of Shentong Zhuyutang benchmark samples can be studied by total statistical moment analysis and primary feeding amount analysis， which can confirm the supramolecular "imprinting template" theory to a certain extent.
