Anti-oxidation and anti-aging activity of polysaccharide from Malus micromalus Makino fruit wine

Malus micromalus Makino fruit wine was used as a raw material and a water soluble polysaccharide (MWP-2) was successfully separated from it by fractionated extraction, alcohol precipitation, macroporous resin purification, cellulose column purification, running water dialysis, and vacuum freeze drying. The structure of MWP-2 was preliminarily analyzed by high performance gel-permeation chromatography (HPGPC), ion chromatograph (IC) and FT-IR....
