Abstract: Lychee, as a typical fruit of South China, was popular in domestic and oversea markets for its
delicious tastes and health promoting effects. In recent years, a lot of studies have focused on the
bioactive components and health effects of lychee. This paper summarized the chemical structures and
distribution characteristics of polyphenols and polysaccharides in lychee pulp. Procyanidines and
flavonoids were the main polyphenols in lychee pulp while heteropolysaccharides were the main
polysaccharides, which possessed a large number of fractions with different molecular weights and
structures. Lychee pulp with different cultivars had different polyphenols and polysaccharides contents
while feizixiao and nuomici were the best cultivars. The antioxidant, hepatic protection, lipid metabolism
improvement, and immunomodulatory activities and their action mechanisms of polyphenols and
polysaccharides were summarized. Moreover, changes of polyphenols and polysaccharides during the
process of lychee were introduced. This review will provide inferences for the lychee蒺s intensive process.
Keywords: lychee pulp; phenolic; polysaccharide; chemical characterization; bioactivity; chang during
