Abstract

Marine ecosystems can be considered as a rather unexplored source of drugs as well as a surprising reservoir of
bioactive oligosaccharide. Marine oligosaccharides could be obtained by hydrolysis of polysaccharide existing in
a variety of biomass sources or synthesized by simple oligosaccharides. In recent years, marine oligosaccharides
which degraded by polysaccharides are attracting increasing interest in developing potential drugs for chronic
diseases. Significant efforts have been made to find and confirm their bioactivity such as anti-tumor, antimicrobial,
antioxidant, anti-inflammatory and so on. In this review, the mechanisms of bio-function eliciting kinds of
applications of different marine oligosaccharides are summarized.
