Recent advances in polysaccharopeptides from Trametes versicolor: Extractions, structural characteristics,...

Trametes versicolor, a traditional medicinal fungus in China, shows broad application prospects in modern medicine and the health industry. T. versicolor polysaccharopeptides (TVPPs) are among its core bioactive constituents and exhibit notable pharmacological activities in immunomodulation, antitumor, antiviral, anti-obesity, and hepatoprotective effects; their biological functions and application value have attracted considerable attention. At present, the extraction and structural characterization methods for TVPPs become relatively mature. Different TVPPs contain high levels of glucose and acidic amino acids, and these structural characteristics are closely related to their functional performance. Although existing studies have conducted preliminary analyses the chemical structures, they remain insufficient to systematically elucidate correlation between molecular structure and biological function. The review provides a comprehensive overview of recent developments in research on TVPPs, focusing on their extraction processes, chemical features, bioactivity, and their intrinsic relationships, and provides prospects for future research directions and industrial applications, with the aim of offering comprehensive theoretical references and technical support for subsequent related studies.
