ABSTRACT
Hyaluronic acid is widely used in biomaterials, cosmetics, clinical medicine and other fields due to its good biocompatibility, degradability, hydrophilicity, tumor targeting, viscosity and other characteristics. Pharmacodynamic activities of natural small molecular products which derived from traditional Chinese medicine (TCM) are significant, but their low solubility and poor targeting limit the clinical application. Based on supramolecular properties of hyaluronic acid, in this review, numerous studies were reviewed on the improvement of solubility, bioavailability, targeting and suitable dosage forms of small molecular compounds in TCM by domestic and foreign scholars using hyaluronic acid as carrier. It provides new ideas and inspirations for exploring the potential application value of small molecule compounds in TCM and even for the research and development of new drugs.
