大豆新型营养因子亚精胺的研究进展

Progress on Study of Spermidine as A New Trophic Factor in Soybean

亚精胺是在大豆中发现的又一功能性营养因子,作为一种无毒的天然物质,可通过诱导自噬作用发挥抗衰老和延长寿命的功能,同时对神经变性还具有抗氧化和消炎作用。大豆种子中亚精胺含量水平较一般谷类、蔬菜、块根农作物等植物高,研究表明大豆食品中亚精胺含量更高,说明大豆品种亚精胺含量对大豆食品保健功能起着重要作用。本文从亚精胺的营养保健作用、亚精胺含量检测方法、亚精胺在植物抗逆中的生理作用和大豆及其制品中亚精胺的研究进展4个方面进行了综述,以期为高亚精胺含量大豆材料的筛选、开展大豆亚精胺基因挖掘、选育高亚精胺含量大豆品种及开发大豆保健食品提供参考。

The soybean seeds contain spermidine, which is another new functional trophic factor in soybean. Spermidine is a nontoxic natural substance, which has function of anti-aging and prolong life by inducing autophagy. It also has antioxidant and anti-inflammatory protective effects. The spermidine content of the soybean seeds is higher than that of cereals, vegetables, root crops, etc. Furthermore, soy foods contain higher levels of spermidine. The content of spermidine in soybean varieties is more important to the health function of soy foods. Four aspects about the study of spermidine were summarized in this paper, including the trophic and health functions, the detection methods, the physiologic function of stress resistance in plants, and the research progress of spermidine in soybean seeds and soy foods. These will provide reference for the gene mining, developing soybean varieties with high spermidine content and exploiting health soy food.
