The aim of this study was to the prepare the standard decoction of paeoniae radix rubra for its investigation of quality standard.The standard decoction of paeoniae radix rubra was dissolved by water using standardization method and the content of peoniflorin was determined by UPLC-DAD.Then the transfer rate and the rate of extractum were calculated,and the fingerprint analysis was carried out.As a result,the content of the standard decoction of paeonia lactiflora ranged from 3.79 to 5.68 mg·mL-1 from 15 paeoniflorin batches,while the transfer rate ranged from 56.58％ to 90.14％,and the average transfer rate was 73.97％ and the standard deviation was 10.91％.The rate of extractum ranged from 16.74％ to 29.24％,the average yield was 21.82％ and the standard deviation was 3.55％.There were eleven common peaks,four of which were identified,including oxypaeoniflorin,albiflorin,paeoniflorin and benzoylpaeoniflorin.In conclusion,it was demonstrated that the method was simple with good repeatability for the preparation and quality standard studies of the standard decoction of paeoniae radix rubra.

Objective:To study the dry extract rate,determination and transfer rate of maker compounds,fingerprint and others of standard decoction of Chrysanthemi Indici Flos and provide basic data for the preparation of this standard decoction and its dispensing granules by establishing 15 batches of standard decoction of Chrysanthemi Indici Flos from 5 different places. Method:The standard decoction of Chrysanthemi Indici Flos was prepared based on the traditional decoction process,the content of linarin was determined by UPLC-DAD,the transfer rate of this composition was calculated,the fingerprint was drawn,the extract powder was prepared by vacuum drying,and the dry extract rate was calculated. Result:The concentration of linarin in 15 batches of standard decoction of Chrysanthemi Indici Flos was 0.19-0.74 g·L^-1,the transfer rate of linarin was 21.95%-66.23%,its average transfer rate was 37.12% with RSD of 11.8%,the pH value was 5.1-5.5,the range of dry extract rate was 24.7%-32.5%,the average dry extract rate was 27.87% with RSD of 2.4%.There were 9 major common peaks in the fingerprint and 2 peaks(No. 2 and No. 9) were confirmed,such as chlorogenic acid and linarin. Conclusion:The preparation method in this research conforms to the traditional decoction method and is stable and feasible.It can be used for the preparation and quality evaluation of standard decoction of Chrysanthemi Indici Flos.

This paper discusses the research situation of the standard decoction of medicinal slices at home and abroad. Combined with the experimental data, the author proposes that the standard decoction of medicinal slices is made of single herb using standard process which should be guided by the theory of traditional Chinese medicine, based on clinical practice and referred to modern extraction method with a standard process. And the author also proposes the principles of establishing the specification of process parameters and quality standards and established the basis of drug efficacy material and biological reference. As a standard material and standard system, the standard decoction of medicinal slices can provide standards for clinical medication, standardize the use of the new type of medicinal slices especially for dispensing granules, which were widely used in clinical. It can ensure the accuracy of drugs and consistency of dose, and to solve current supervision difficulties. Moreover the study of standard decoction of medicinal slices will provide the research on dispensing granules, traditional Chinese medicine prescription standard decoction and couplet medicines standard decoction a useful reference.
