On the basis of the qualitative preparation quality markers of Yulian Decoction, we screened out the quantitative markers and explored a general strategy for analyzing the component migration in Chinese herbal pieces, preparations, and plasma. A method capable of simultaneously determining 28 chemical components in Yulian Decoction was established based on HPLC-MS/MS. This method was used to determine the migrated components in herbal pieces-lyophilized powder preparations-rat plasma after administration of Yulian Decoction.

Classical Representative Famous Prescription is the valuable cultural heritage of Chinese medicine. In November 2018,the State Council issued the " Intensive Implementation of the National Intellectual Property Strategy in 2018 to Accelerate the Construction of IP Strong Country",explicitly proposing to strengthen the intellectual property protection of Classical Representative Famous Prescription.How about the current situation of intellectual property protection of lassical Representative Famous Prescription in China? We selected Liuwei Dihuang Pills,Shengmai Powder and Guizhi Fuling Pills( three representative drugs on market) from Chinese Pharmacopoeia2015 Volume I issued by Chinese Pharmacopoeia Commission to analyze their patent layout,reflecting its status quo of patent protection as follows: first,in recent years,the number of related patent applications for Classical Representative Famous Prescriptions has declined,which was positively correlated with the drug registration and approval policies in recent years,but the policy dividend has not been reflected in the patent application,which may be related to the long period of pharmaceutical R&D; secondly,the patent applicant in the field of Chinese medicine is mainly based on individuals,but the applicant of Classical Representative Famous Prescription is mainly of enterprises,and in addition,the company applicants have the highest authorization rate; thirdly,the main technologies are to improve preparation method and the dosage form in the research and development of Classical Representative Famous Prescription,but these two types of authorized patents have much difficulty in further application on the market.

In this paper, classic preparations in Treatise on Febrile Diseases were systematically investigated to obtain their process parameters, and provide literature evidence and technical support for drug research and development. This paper includes the following sections: drug dose, solvents, excipients, and process parameters of classic preparations. The drug dose in Treatise on Febrile Diseases was not consistent with that in Pharmacopoeia of the People's Republic of China 2015, for example, "Yi-Liang" was about 15.

To evaluate in vitro release and transdermal behaviors of Huoxue Zhitong gel, modified Franz diffusion cell methods was applied to investigate in vitro transdermal absorption of Huoxue Zhitong gel and the content of paeonolan in receptor fluid composed of PEG400%-95% ethanol-water (l:3:6)were determined by HPLC. The results were processed and different equations were fitted. The release law were in accordance with Weibull equation and the fitting equation was In[-1/(1 - Q)] = -0.

Objective: To establish a LC-MS/MS method for determining the concentration of tanshinone IIA, salvianolic acid B and paeoniflorin of refined coronary cataplasm in rabbit plasma, in order to determine the concentration of the three main ingredients in blood after transdermal administration and calculate their pharmacokinetic parameters.

Method: Rabbits were given refined coronary cataplasm on the basis of 15 g x kg(-1) by transdermal administration to detect the plasma concentration of the three main ingredients using LC-MS/MS. Winnonlin software was used to calculate their major pharmacokinetic parameters.
