The standard decoction of Chinese herbal decoction pieces is a standard reference substance to measure whether different dosage forms of Chinese medicine are basically consistent with those of clinical decoction,and provides new ideas and methods for effectively solving the problems of uneven quality in Chinese medicine dispensing granules. In this study,a systematic method for evaluating the quality of Scrophulariae Radix decoction was established from the perspective of " standard decoction",providing reference for the quality control of the Scrophulariae Radix dispensing granules. 15 batches of Scrophulariae Radix decoction pieces from different origins were collected,and 15 batches of standard decoctions were prepared according to the standardized process with water as solvent.Harpagide and harpagoside were used as quantitative detection indicators to determine the content,calculate the transfer rates and determine the extraction rate. The high performance liquid chromatography( HPLC) was used to establish a standard decoction fingerprint analysis method. The results showed that the transfer rates of harpagide and harpagoside in 15 batches of Scrophulariae Radix pieces standard decoction were( 70. 84±13. 39) % and( 48. 56±6. 40) % respectively; the extraction rate was( 57. 47±5. 89) %. Nine peaks were identified in the HPLC fingerprint,and the similarity was higher than 0. 97 between the fingerprints of 15 batches of standard decoction and the control fingerprint. In this study,the preparation process of standard decoction of Scrophulariae Radix pieces conformed to the traditional decoction preparation method. The sources of the samples were representative,and the established fingerprint method was stable and feasible,which can provide reference for the preparation and quality control of Scrophulariae Radix dispensing granules.
