Abstract Longan originates from southern China and has high nutritional and health value. Recent phytochemistry and
pharmacology studies have shown that polysaccharides are a main bioactive component of longan. Longan polysaccharides possess antioxidant, anti-aging, anti-tumor, immunomodulatory, and other bioactivities. Hot-water
extraction, ethanol precipitation, and ultrasonic extraction are generally used to extract water-soluble longan
polysaccharides. However, the relationship between the structure and bioactivity of longan polysaccharides
remains unclear, requiring further investigation. The aim of this review is to evaluate the current literature focusing on the extraction, purification, structural characterization, and biological activity of longan polysaccharides.
