Abstract:Ginger （Zingiber officinale Rosc.），as a dual-purpose resource of medicine and food，is widely used in China.It contains a variety of bioactive components，such as polysaccharides，polyphenols，terpenoids，and gingerol and its derivatives.Among these，ginger polysaccharides have become a research hotspot in recent years owing to their various biological activities，such as antitumor，antioxidant，hypoglycemic，anti-cough，and antifatigue effects.In this study，research on the extraction，structural characterization，and biological activity of ginger polysaccharides was reviewed to provide a reference for the rational development and utilization of ginger and its polysaccharides.
