Abstract

The invention discloses amomum villosum rhizome polysaccharide as well as a preparation method and antioxidant application thereof. The amomum villosum rhizome polysaccharide AVRP-1 is obtained by extracting amomum villosum rhizome crude polysaccharide and then purifying the amomum villosum rhizome crude polysaccharide through sephadex column chromatography. The AVRP-1 has antioxidant activity, the half effective concentrations (EC50) of DPPH and hydroxyl radicals are 4.50 mg / mL and 2.47 mg / mL respectively, the AVRP-1 is expected to be developed into functional food and health care medicine, the amomum villosum can be fully utilized, waste is turned into wealth, the overall economic value of the amomum villosum is improved, and income is increased.

Description
