| 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. |
