中文摘要:

      甘薯作为我国的一种重要粮食作物, 曾经在抵抗饥荒、保障粮食安全方面发挥过重要作用。近年来, 甘薯在我国食品利用方面的作用逐渐发生了改变, 许多以甘薯为原料的新型食品被开发了出来。与此同时, 对甘薯的营养和保健功效的研究也越来越多, 发现甘薯块根及茎叶中均含有许多具有特殊生物活性的物质, 如糖蛋白、胰蛋白酶抑制剂、凝集素、花青素、咖啡酰奎宁酸、香豆素、类胡萝卜素等。这些生物活性成分分别具有清除体内自由基及活性氧、抑制炎症、降血糖、降血脂、提高免疫力、减轻肝损伤、抑制肿瘤细胞增殖和浸润等多种生物学功能, 可在预防和辅助治疗疾病方面发挥重要作用。本文对甘薯中所含有的主要生物活性成分及其生物学活性的研究现状进行综述, 以更好地促进相关研究的开展。

英文摘要:

      As a kind of important food crop in China, sweet potato has played an important role in resisting famine and ensuring food security. In recent years, the role of sweet potato in China's food utilization has gradually changed, and many novel foods that use sweet potato as a raw material have been developed. At the same time, more and more researches on the nutrition and the health promotion effects of sweet potato have been carried out. It was found that the root, stem and leaves of sweet potato contained many kinds of special bioactive substances, such as glycoproteins, trypsin inhibitors, lectins, anthocyanins, caffeoylquinic acid, coumarins, carotenoids, etc. These bioactive components had been shown to be able to scavenge free radicals and reactive oxygen, inhibit inflammation, reduce blood sugar and lipid, improve immunity, reduce liver damage, and inhibit tumor cell proliferation and infiltration as well as many other biological functions, so they might possibly play important roles in the prevention and adjuvant treatment of many diseases. This paper reviewed the research status of the main bioactive components in sweet potato and their biological activities as well, so as to facilitate the development of related researches.
