北五味子粗多糖对果蝇寿命的影响

THE EFFECTS OF CPSC ON THE LIFESPAN OF DROSOPHILA MELANOGASTER

目的:研究北五味子粗多糖对果蝇寿命的影响。方法:将含有不同质量浓度(0.1%、0.3%、0.9%)的北五味子粗多糖培养基经口喂养美国黑腹果蝇,以普通培养基作为空白对照,观察其对果蝇寿命的影响。结果:各浓度的北五味子粗多糖能够延长雌、雄性果蝇的平均寿命(雄果蝇增加7.98%、14.19%、6.86%,雌果蝇增加13.53%、20.70%、11.33%)、最高寿命和半数死亡时间。结论:北五味子粗多糖具有一定延缓衰老的作用。

Objective：To study the effects of the coarse polysaccharides from schisandra chinensis（CPSC） on the lifespan of Dro-sophila melanogaster.Methods：Drosophila melanogaster were fed with different concentrations of CPSC（0.1%, 0.3% and 0.9%） and normal medium was used as a control group.The lifespan of Drosophila melanogaster were observed.Result：CPSC prolonged female and male Drosophila average lifespan（ male drosophila increased by 7.98%, 14.19%, 6.86%; female drosophila increased by 13. 53%, 20.70%, 11.33%）, maximum lifespan, half death time.Conclusion：CPSC had the function of delaying consenescence.
