Objective: To investigate the effect of Maca polysaccharide on the life span and antioxidative ability of Drosophila melanogaster. Method: Eight hour eclosion unmated D.melanegaster were collected.Male and female were separated
D.melanogaster were randomly divided into 4 groups:control group
Maca polysaccharide group (0.03
0.08
0.24 g·L-1). The life span
the survival time in paraquat and hydrogen peroxide treatment
the activities of superoxide dismutase (SOD)
catalase(CAT)and the content of lipofuscin were determined. Result: Compared with the control group
the high dose group extends the maximum life span and mean life span of D. melanogaster(P<0.05 or P<0.01)
exhibiting a dosage effect. The middle dose group and the high dose group can improve the survival time in paraquat and hydrogen peroxide treatment. The activities of SOD and CAT increase
meanwhile the content of lipofuscin decreases in the experiment. Conclusion: Maca polysaccharide might have a satisfactory effect on life span and anti-oxidant.
