摘要: 以野生型黑腹果蝇为对象,用含不同浓度EGCG(20、40、80μL/L)的培养基对果蝇进行生存试验。统计果蝇存活数和死亡数,计算半数死亡时间、最高寿命和平均寿命,观察EGCG对雌、雄果蝇寿命的影响。结果表明,随着EGCG作用浓度的提高,能有效延长雌雄果蝇半数死亡时间、最高寿命以及平均寿命,当EGCG浓度为40μL/L时为延长雌果蝇寿命的最佳浓度。

Abstract: Wild-type Drosophila melanogaster was cultured with different concentrations of EGCG (20, 40 and 80 μL/L) of medium for the survival experiments. The numbers of survival and death of Drosophila melanogaster were recorded, and the median death time, the maximum life span and average life were calculated. Results showed that the median death time, the maximum life span and average life of male and female Drosophila melanogaster could be prolonged effectively with the increase of EGCG concentration, and 40 μL/L was the optimum concentration of EGCG to prolong the life-span of female Drosophila melanogaster.
