| 中文摘要: |
| 作为大脑神经纤维和神经细胞的核心成分，超长链单不饱和脂肪酸神经酸(Nervonic acid，NA)具有修复受损大脑神经纤维、促进神经细胞再生的功能。人体内缺乏神经酸会引起失眠健忘、脑萎缩，甚至脑瘫等脑疾病。虽然近30年来我国对神经酸植物的开发利用取得了显著进展，但是仍然未能解决神经酸缺乏的问题。笔者经大量检测发现，神经酸普遍存在于我国的甘蓝型、白菜型、芥菜型油菜籽中，对2017—2019年4 159份甘蓝型油菜资源种子的神经酸与芥酸含量进行分析，发现神经酸含量与芥酸含量存在正相关关系。综述了我国含神经酸植物的开发与利用情况及神经酸的合成与芥酸的关系，分析探讨了菜籽油中芥酸的有益价值，对选育并规模化开发利用高神经酸含量油菜品种作为神经酸来源新方向，从而解决目前神经酸原料缺乏的问题进行了探讨。 |

| As the core component of brain nerve cells and nerve fibers, nervonic acid, which is a kind of very long chain monounsaturated fatty acid (VLCMFA), can repair damaged brain nerve fibers and promote nerve cell regeneration. The deficiency of nervonic acid can lead to brain diseases such as insomnia, forgetfulness, brain atrophy,even cerebral palsy. Although remarkable progress has been made in the development of plants rich in nervonic acid in China in the past 30 years, the problem of lack of nervonic acid has not been solved. Through a large number of tests, it was found that the content of nervonic acid was common in rapeseed oil of Brassica napus, Brassica campestris and Brassica juncea in China. The fatty acid composition of 4 159 Brassica napus resources seeds in 2017—2019 was analyzed. There was a positive correlation between the content of nervonic acid and erucic acid. The development and utilization of natural neuronic acid-containing plants in China and the relationship between the synthesis of nervonic acid and erucic acid were summarized, the benefits of erucic acid in rapeseed oil was discussed, the breeding and large-scale development of rape varieties rich in nervonic acid as a new source of nervonic acid to solve the current problem of lack of nervonic acid raw materials were discussed. |
