We investigated the antioxidant effects of
Camellia sinensis
(tea)
polysaccharides in exhausting training mice. Three groups of
mice were fed with C. sinensis (tea) polysaccharides
(100, 200 and 300 mg/kg, respectively). The results showed that
plasma, lever and heart MDA level were reduced after 30 days of
C. sinensis (tea) polysaccharides treatment. Compared
with control mice, blood, liver and heart superoxide dismutase
(SOD), catalase (CAT), GPx activities were significantly
increased after 30 days of C. sinensis (tea)
polysaccharides treatment. Overall, both extracts of C.
sinensis (tea) polysaccharides possessed good antioxidant
properties and can be developed as antifatigue medicine.
Key words:
