EXTRACTION AND ANTI-OXIDATION ACTIVITY OF POLYSACCHARIDES FROM LENTINAN

Men Cheng-Bai, Wu Mei-Fu, Zhou Hong-Li

ABSTRACT:The extraction and anti-oxidation activity of polysaccharides from Lentinan were studied by an orthogonal experimental design. The optimal extraction process was solid-liquid ratio = 1:20, pH 5, 60 ºC and extraction time=3 h, with the extraction yield of 11.61%. It was proved this extraction method was simple and available, and the crude polysaccharides had high antioxidant capacity.
