Abstract:

Based on single factor studies, a three-variable, three-level Box-Benhnken experimental design and response surface methodology were employed to optimize the extraction process of water-soluble polysaccharides from the shoot of Lygodium japonicum. Response surface and contour plots with polysaccharide yield as a function were obtained, and process conditions were analyzed for their significance for polysaccharide extraction and significance analysis of their interactions was also done. Extraction temperature of 92 ℃ and solid/liquid ratio of 1:25 for twice extraction for 2.1 h each time were found optimal. Under such conditions, a polysaccharide yield of 16.475% was obtained.

Key words: Lygodium japonicum, polysaccharide, extraction, response surface methodology
