中文摘要：

以果蝇为动物模型，对玫瑰花提取物（F21）进行抗氧化防衰老的研究．通过大样本、高重复的寿命实验，证明了F21能显著提高果蝇的平均寿命和最高寿命．用F21饲养（培养基给药浓度0．2％）果蝇后，其处理组果蝇体内的脂褐素含量明显下降、飞行频率有明显的升高趋势；同时，果蝇体内抗氧化酶CAT和SOD的活力均有明显提高．

英文摘要：

In the present researches, Drosophila melanogaster was introduced as the model that was used to investigate the antioxidant activities and anti-ageing actions of F21 from Rosa Rugosa. By the life span experiment with a mass of swatches and repetitions, it was testified that F21 obviously increased the average and the longest lifespan of treated fruit fly. After Drosophila melanogaster were treated with F21（0. 2 % concentration）, the content of Lipofuscin obviously decreased compared to control group, while the flight frequency obviously increased. The activities of CAT and SOD increased after fruit fly was treated with F21.
