Structural characterization and immunomodulatory activity in vitro of an arabinogalactan from the pulp of Siraitia grosvenorii.
An arabinogalactan (SGP80-A1) was isolated for the first time from the pulp of Siraitia grosvenorii, with an apparent Mw of 81.3 kDa. Its structure was initially characterized using an integrated strategy combining NMR spectroscopy with database matching, allowing non-destructive identification of sugar residue types d...
