AI Article Synopsis
- The study examined how individual and combined treatments of epi-brassinolide (eBL) and sodium chloride (NaCl) affect the phytochemical content and antioxidant capacity of Chinese kale sprouts.
- The application of 100 nM eBL decreased glucosinolate levels, while 160 mM NaCl increased glucosinolate accumulation by enhancing related gene expression.
- The combined treatment of 100 nM eBL and 160 mM NaCl significantly boosted glucosinolates, ascorbic acid, and total carotenoids, presenting a potential method to enhance the health benefits of Chinese kale sprouts.
Article Abstract
The effects of individual epi-brassinolide (eBL) and NaCl, as well as their combination on contents of main phytochemicals and antioxidant capacity of Chinese kale sprouts were investigated. Our results showed that the application of 100 nM eBL decreased the contents of individual and total glucosinolates, while treatments of 160 mM NaCl both alone and combined with 100 nM eBL enhanced the glucosinolates accumulation by promoting the expression of genes involved in glucosinolate biosynthesis in Chinese kale sprouts and the combined treatment led to significantly higher content of most glucosinolate profiles. Moreover, it also elevated the contents of ascorbic acid and total carotenoids, whereas did not influence the total phenolics and antioxidant capacity. These findings indicated that the combined treatment of 100 nM eBL plus 160 mM NaCl could provide a new strategy to improve the main health promoting compounds in Chinese kale sprouts.
