Abstract:The fruit of Gardenia jasminoides Ellis is among the first batch of resources that can be used as both medicine and food released by National Health Commission of China.It is widely applied and can be further developed.Polysaccharides，as one of the main effective components of G.jasminoides fruit，possess complex chemical structure and diverse biological functions，such as anti-inflammation，anti-oxidation，anti-tumor and immunization.This study reviewed the preparation methods，chemical structure and bioactivity of polysaccharides from G.jasminoides fruit and summarized the research on the polysaccharides，which is expected to provide a theoretical reference for further research.
