摘要: 以秀丽隐杆线虫(Canorhabditis elegans)为模式生物研究山楂提取物(Haworth fruit extract,HFE)对其急性氧化损伤的保护作用及其可能的作用机制。饲喂线虫于含有不同浓度(0、25、50和100 μg/mL)HFE的NGM(Nematode growth medium)培养基中,研究HFE对线虫急性应激耐受能力的影响。结果显示,饲喂HFE后,秀丽线虫表现出比正常组更高的寿命,并且在胡桃醌氧化应激、热应激及紫外辐射应激实验中寿命均明显延长,荧光显微镜观察发现HFE组线虫的脂褐素自发荧光明显减弱,并且与HFE浓度呈剂量依赖效应。 HFE能够显著延长秀丽隐杆线虫的寿命,同时对多种氧化损伤具有较好的保护作用,改善机体的抗氧化能力,有效延缓衰老。

Abstract: The work aims to study the protective effect of haworth fruit extract(HFE)on the acute oxidative damage and its possible protection mechanism in Caenorhabditis elegans. The C. elegans were fed with nematode growth medium(NGM)containing different dose of HFE(0,25,50 and 100 μg/mL)to study impacts of HFE on the acute stress tolerance. C. elegans with feeding in different dose of HFE had a longer lifespan than the normal group,moreover,their lifespans became significantly longer under the experiments of juglone oxidative stress,heat stress and UV radiation stress. Concurrently,the autofluorescence level of lipofuscin in HFE group of C. elegans significantly decreased and it was dose-dependent effect to the concentration of HFE. In conclusion,HFE significantly prolongs the lifespan of C. elegans and has a solid protection under a variety of oxidative stress conditions with improving the antioxidant capacity and efficient anti-aging
