The course of " Traditional Chinese Medicine Analytics" of Shanghai University of Traditional Chinese Medicine was listed as the Shanghai Key construction course in 2017, was selected as the Shanghai first-class course in 2021, and was selected as the national first-class course in 2023. This article reviews the knowledge points of identification analysis, quantitative analysis, inspection, fingerprint, and specific chromatogram in the course of " Traditional Chinese Medicine Analytics" which are integrated to the virtual simulation experimental projects to construct a knowledge map for this course. With gas chromatography as an example, this article introduces the ideas for constructing virtual simulation experimental projects of gas chromatography analytical techniques in traditional Chinese medicine and evaluates the teaching effect from the dimensions of the degree of student completion, learning performance, and error rate, so as to lay a solid foundation for promoting the integration of virtual simulation technology into the construction of core courses, continuously improve the quality of classroom teaching, and achieve the goal of winning in the classroom.

Decoction is a traditional clinical way of traditional Chinese medicine （TCM） compound. A series of complex physical and chemical changes are often involved in the process of decoction， which presents a mixed-phase system. In most studies on the TCM compound decoction， it has always focused on the amounts of chemical substances in decoction， while the phase properties and existence forms of these components are neglected. Most of the chemical components exist in the mixed-phase system as molecules， ions or other particles. According to the particle size of the contained particles， the differences among the phases， including true solution phase， colloidal phase， suspended phase and precipitated phase， lead to their differences in pharmaceutical and biological effects. Based on the above research background， this paper takes the phase state differences of decoction as the breakthrough point， and systematically reviews the physicochemical properties， the physical structures of the active components and the biological effects of the decoction caused by the phase state differences. The phase state differences of TCM compound decoction have been found to be closely related to their efficacy， which might be a good perspective to investigate the possible mechanism. It might provide a beneficial reference for the exploration of related basic research on TCM compounds.
