The water extraction and alcohol precipitation were selected to extract polysaccharides from illicium verum leaves and the phenol-sulfuric acid method was used to determine the polysaccharide content. The optimal extraction process was selected with the orthogonal test design.The optimal extraction process was extraction temperature 75℃ , with 2h, with 1:50 (g /mL) of illicium verum leaves weight to distilled water and extraction for 2 times. The optimum extraction rate o f polysaccharide from illicium verum leaves was 12.87% and the total content of crude polysaccharides was 28.22%.
