Abstract

This study was carried out to investigate the technology of extracting Lycium barbarumpolysaccharide (LBP) and its antioxidation activity, using orthogonal experimental method to optimize its extraction conditions. Fenton reaction and pyrogallol experimental method were adopted to determine the antioxidation activity of LBP. The three factors investigated in the orthogonal experiment affected the results. Different concentrations of LBP effectively cleared hydroxyl radical (OH-) and superoxide anion (O2+). It was concluded that the extraction of LBP by cold maceration as well as the three factors, (solvent volume, extraction time and extraction times) affects its yield, and that it has antioxidation activity.

 

Key words: Lycium barbarum polysaccharides, antioxidation activity.
