[Quality evaluation of medicinal herb decoction--Forsythiae Fructus].

To establish the quality control methods for the standard decoction of Forsythiae Fructus. Twelve batches of representative Forsythiae Fructus were collected to prepare standard decoction of Forsythiae Fructus, and then the parameters such as extraction ratio, transfer rate of the index components and pH value of the solution were calculated to evaluate the stability of the process. The simultaneous determination method of target components and fingerprint method were established, and ultra performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS) was used to identify the main common peaks in the fingerprint to clarify the main chemical constituents in the decoction.

[Quality evaluation of Rhei Radix et Rhizoma decoction].

Decoction of single medicinal herb is a reference for the standardization of different dosage forms of Chinese medicine and it provides a new direction for solving the problems existing in the quality of Chinese medicinal granules such as no uniform dosage form and no clear quality standard. In this paper, the quality evaluation method of standard decoction of rhubarb was established to provide reference for the quality control of common dosage forms such as clinical decoction and formula granule. 10 batches of representative Rhei Radix et Rhizoma were collected to establish UPLC fingerprints were established.

The effect of ethanol extract of Glycyrrhiza uralensis on the voltage-gated sodium channel subtype 1.4.

To investigate the inhibitory effect of Glycyrrhiza uralensis (G. uralensis) and its monomeric compounds on Nav1.4 voltage-gated sodium channels (VGSCs) and analyze the relationship between the content of its marker compounds and the inhibitory rate.

[Research strategies in standard decoction of medicinal slices].

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.
