Abstract: This Study is about the effects of lycopene on median lifespan and maximal lifespan in drosophila and the scavenging effect on superoxide negative ion、oxyhydrate of lycopene. The experiment also determines SOD and MDA value. Exploit Ames experiment to determine if the lycopene has heredity toxicity. The result shows that Lyp in the medium significantly prolonged median lifespan of male and female drosophila melanogsters, as well as female maximal lifespan. Lyp also has strong scavenging effect on the above free radical, and the does-effect relationship is significant. Then Lyp has no toxicity.
