Abstract:
Extraction conditions for polysaccharide from Rapana venosa were optimized by orthogonal test. The effects of factors, including extraction time, solid to solvent ratio and extraction temperature were investigated using single factor analysis and orthogonal analysis. The results showed that the best conditions for extraction of polysaccharide from Rapana venosa were: extraction temperature 50 ℃; solid to solvent ratio 1:80 (m/V) and extraction time 30 min, under which the polysaccharide yield reached 21.8%.
