Abstract: As the main chemical component of aromatic traditional Chinese medicine (TCM), the volatile oil of TCM has significant pharmacological effects, such as antibacterial, anti-inflammatory, antioxidant and so on. However, TCM volatile oil is easy to volatilize and oxidize, which seriously limits its application. As a kind of grid structure material, porous material has the characteristics of high specific surface area, large pore volume, adjustable pore size, strong adsorption capacity and controllable surface chemical properties. It has been widely used in adsorption separation, biomedicine, industrial catalysis, wastewater treatment and other fields. In recent years, the use of porous materials to adsorb volatile oil has provided a new strategy and method for improving the stability of TCM volatile oils. At the same time, it can realize the solidification and stability of TCM volatile oils and the application of preparations. In this review, the development and characteristics of porous materials such as mesoporous silica, mesoporous carbon, mesoporous nano hydroxyapatite, porous metal organic framework, porous starch and their application in improving the stability of TCM volatile oils are summarized, and the research strategies affecting the adsorption stability of porous materials for TCM volatile oils are discussed, in order to provide reference for the stabilization control and application of TCM volatile oils.
