Objective To establish the HPLC fingerprint and multi-component determination for substance benchmark of Zhuye Shigao Decoction (竹叶石膏汤, ZSD), evaluate its quality in combination with chemical pattern recognition method and explore the mass transfer law of substance benchmark. Methods The substance benchmark of 20 batches of ZSD was prepared based on ancient medical records, the HPLC fingerprint was established, the attribution of common peaks was clarified, and the ointment rate of the whole prescription was determined. The components content and transfer rate of isoorientin, ginsengside Rg1, ginsenoside Re, ginsenoside Rb1, liquiritin and glycyrrhizic acid were measured and the transfer analysis of substance benchmark was performed. Results The similarity of the 20 batches of ZSD material benchmark fingerprint were all greater than 0.90, and a total of 21 characteristic peaks were identified, which came from Lophatherum gracile (six peaks), Ophiopogon japonicus (six peaks), Pinellia ternata (three peaks), and Glycyrrhiza uralensis (six peaks). The samples can be divided into four categories by chemical pattern recognition methods. The transfer rate of each index component from the decoction pieces to the substance benchmark was in the range of isoorientin:31.94%-50.91%, glycyrrhizin:35.77%-62.55%, licorice acid:13.09%-22.63%, ginsenoside Rg1:57.28%-83.95%, ginsenoside Re:42.21%-72.27%, ginsenoside Rb1:38.19-64.57%; The creaming rate ranges from 16.99% to 27.06%. Conclusion In this study, the fingerprint combined with multi-index content determination and chemical pattern recognition were used to carry out the quantity value transfer analysis of the substance benchmark of ZSD. This method is scientific and reasonable, and can provide a reference for subsequent formulation development.
