Comparison of Antioxidant Activities of Auricularia auricular Polysaccharides from Different Producing Areas
摘要
Abstract
To promote the further development and utilization of Tongjiang Auricularia auricular,three kinds of A.auriculus from different producing areas in Northeast Xiaowan Auricularia,Tongjiang A.auricular and Baibei A.auricular were studied.With extraction rate and polysaccharide content as evaluation index,A.auricular polysaccharides were obtained by hot water extraction and Sevag deproteinization,respectively.The different of A.auricular polysaccharides from different producing areas were investigated by Molish reaction.And the antioxidant activities of polysaccharides from different producing areas were investigated by in vitro.The results showed that the extraction yield and polysaccharides content of Northeast Xiaowan Auricularia were the highest,2.48％and 43.64％,respectively,which indicated that Northeast Xiaowan Auricularia had advantages of extraction rate and polysaccharide content.A.auricular polysaccharides from different producing areas had different antioxidant activities,and Tongjiang A.auricular had obvious advantages in antioxidant activities,the scavenging rates of hydroxyl free radical,DPPH free radical,and ABTS+·free radical were up to 50.11％,56.68％,32.64％,respectively,the reducing power was as high as 0.12,which indicated that Tongjiang A.auricular polysaccharides had high antioxidant activities.关键词
