以芥蓝芽为试材，研究了表油菜素钠（eBL）和NaCl单独处理及其复合处理对芥蓝芽中主要植物化学物质含量和抗氧化能力的影响。我们的研究结果表明，100 nM eBL的应用降低了单个和总的硫代葡萄糖苷的含量，而160 mM NaCl单独处理和与100 nM eBL组合处理通过促进参与硫代葡萄糖苷生物合成的基因的表达来增强硫代葡萄糖苷的积累，并且组合处理导致大多数硫代葡萄糖苷谱的含量显著较高。此外，还能提高抗坏血酸和总类胡萝卜素的含量，而不影响总酚和抗氧化能力。这些结果表明，100 nM eBL +160 mM NaCl的组合处理可以提供一种新的策略，以提高中国羽衣甘蓝芽中的主要健康促进化合物。
The effects of individualepi-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.
