目的 :研究刺玫果提取物 (喷雾干燥粉 )对衰老小鼠脑、肝组织中超氧化物歧化酶 (SOD)和丙二醛(MDA)含量的影响。方法 :SOD测定为黄嘌呤氧化酶法 ,MDA测定为硫代巴比妥酸法。结果 :刺玫果提取物可显著增强老龄小鼠脑和肝SOD活性 ,降低MDA含量。结论 :刺玫果提取物具有一定的抗衰老作用
Objective : To study the effects of extracts of Rosa roxburghii (spray-dried powder) on the contents of superoxide dismutase (SOD) and malondialdehyde (MDA) in brain and liver tissues of aging mice. Methods : SOD was determined by xanthine oxidase method and MDA was determined by thiobarbituric acid method. RESULTS : The extract of Rosa roxburghii could significantly increase SOD activity in brain and liver of aged mice and reduce MDA content. Conclusion : Rosa roxburghii extract has anti-aging effect
