[Anti-aging Effect of Urtica Polysaccharides in D-galactose Induced Aging Mice].

Objective: To investigate the anti-aging effect of polysaccharides from Urtica lobatifolia (Urtica polysaccharides) on subacute aging mice induced by D-galactose.

Methods: 90 mice were randomly divided into six groups: normal group, aging mice model group, V(E) group [100 mg/(kg x d), ig], high level of Urtica polysaccharides group [200 mg/(kg x d), ig], medium level of Urtica polysaccharides group [100 mg/(kg x d), ig] and low level of Urtica polysaccharides group [50 mg/(kg x d), ig]. The normal group was injected saline [10 mL/(kg x d), sc], while the other groups were injected D-galactose [150 mg/(kg x d), sc].
