摘要
一项流行病学调查结果显示常饮葡萄酒可能产生预防心血管疾病的作用。葡萄中含有丰富的黄酮类和花色苷类成分,这些物质成分也是水果和蔬菜中大量含有的物质成分,除此而外,果、蔬中的花色素类、黄酮类、多酚类、类胡萝卜素类以及维生素C等主要含量成分是否具有预防心血管疾病的效果,通过对比实验方法说明,属于类胡萝卜素类的番茄红素、花色苷、多酚类以及维生素C也有类似葡萄提取物的抑制LDL氧化效果。因此,多食用水果和蔬菜可能有预防心血管疾病的作用和效果。
An epidemiology investigation, as a result, showed that wine may has the function of preventing the cardiovascular disease potentially, it was French paradox. Grape has rich polyphenol, cyanin and etc. These materials also consist in fruits and vegetables largely, furthermore, flavones, carrotenoids, vitamin C in fruits and vegetables, and whether they have similar thus functions, so we experimented with the extracts from tomato, eggplant, kudzu and tea on the Cu^2＋-mediated oxidative modification of low-density lipoprotein （LDL）. The result was that lycopene could restraint of LDL oxidized violently, flavonoids and vitamin C were as also the effect. Oxidized-LDL was also subjected to electrophoresis, it was affirmed the extracts from these fruits and vegetables inhibited LDL to be oxidated and reduced Ox-LDL. It implies fruits and vegetables are be capable of prevention the cardiovascular disease.
