| 中文摘要 | the non-lichenized ascomycete bulgaria inquinans (fries), growing in the changbai mountain of china, has been used as medicinal diet for many years. in a previous study, we have reported that a heteropolysaccharide biws-4b from the fruit bodies of b. inquinans (fries) exhibited markedly antimalarial and immunostimulating activities. in this paper, the structural features and antioxidant activity of biws-4b were investigated. the results showed that biws-4b contains an alpha-(1 -> 2), (1 -> 6)-mannan core to which the glucogalactan chains are attached. the glucogalactan chains were composed of (1 -> 6)-, (1 -> 5)- and (1 -> 5,6)-linked beta-galf, (1 -> 4)-linked and non-reducing terminal beta-glcp units, and might be attached to the mannan core at the o-2 positions of alpha-manp units. the antioxidant assays showed that biws-4b exhibited good activities, including free radicals scavenging effects, ferrous ion-chelating ability and reducing power. thus, biws-4b could be used as a natural antioxidant agent for food and pharmaceutical industries.
