Antioxidant acitivity in vitro and in vivo of the capsule polysaccharides from Streptococcus equi subsp. zooepidemicus

Purification, composition analysis and antioxidant activity of the polysaccharides from Dendrobium nobile Lindl.

“…Hydroxyl radical is mainly responsible for the oxidative injury of biomolecules (Ke et al, 2009). Fig.…”

A comparison study between different molecular weight polysaccharides derived fromLentinus edodesand their antioxidant activitiesin vivo

“…Production of ROS is essential to many organisms for the production of energy in biological processes (Ke et al, 2009;Zha et al, 2009). However, many human diseases, including aging, cancer, rheumatoid arthritis, and atherosclerosis, are due to the uncontrolled production of excessive free radicals (Mau et al, 2002).…”
