Abstract: Polysaccharide in Actinidia chinensis fruit was sulfated with chlorsulfonic acid-pyridine.Reagent proportion,reaction temperature,and reaction time were selected with substitution degree and yield as index by L9(34)orthogonal design.The results showed that the optimum conditions are:volume ratio of pyridine and chlorine sulfonic acid 2:1,reaction temperature 45℃, reaction time 3 h.

Key words: Actinidia chinensis, sulfated polysaccharide, orthogonal test
