Abstract

Glycyrrhizae Radix et Rhizoma commonly known as liquorice is a traditional Chinese medicinal herb with a long history of use and notable therapeutic value supported by its rich array of biologically active compounds. Among these Glycyrrhiza polysaccharides GLP represent a key class of constituents that exhibit diverse medicinal properties and broad application potential. In recent years GLP has attracted sustained research interest owing to its multifaceted biological activities demonstrating promising prospects in the pharmaceutical and functional food industries. This article systematically reviews the current methodologies for GLP extraction including hot water extraction ultrasonic-assisted extraction microwave extraction and enzyme-assisted extraction as well as separation and purification techniques such as the Sevag method for protein removal decolourisation with macroporous resins fractionated alcohol precipitation and column chromatography. Furthermore it provides a detailed analysis of recent advances in understanding the biological activities of GLP including antioxidant immunomodulatory anti-inflammatory antitumour and gut microbiota regulatory effects. Despite considerable progress in GLP research several challenges remain. These include incomplete structural characterization a lack of systematic studies on structure-activity relationships unclear pharmacological mechanisms and insufficient identification of target molecules and signalling pathways. Moreover the translation of experimental findings into clinical applications is still limited. Future research should focus on applying modern analytical techniques to advance structural studies of GLP integrating molecular biology and metabolomics approaches to clarify its mechanisms of action and strengthening clinical translation to facilitate the efficient utilization of GLP in novel therapeutics and functional foods thus fully realizing its potential.
