Anti-inflammatory activity and structure-function analysis of degraded polysaccharide fragments from Tetrastigma hemsleyanum.
Tetrastigma hemsleyanum Diels et Gilg (T. hemsleyanum) is a medicinal plant with immunomodulatory activity. Its acidic glucuronic acid galactomannan (STHP5, 128 kDa) is degraded into fragments STHP5 DF-1 (78 kDa, helical, 2,3-Manp backbone, the main active fragment). STHP5 DF-1 inhibited NO and inflammatory cytokines,...
