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.

表油菜素内酯和NaCl的联合处理可增强芥蓝豆芽中的主要植物化学物质。

研究了单独的表油菜素内酯（eBL）和氯化钠（NaCl）以及它们的组合对芥蓝芽的主要植物化学成分和抗氧化能力的影响。我们的结果表明，施用100 nM eBL可以降低芥子油苷和总芥子油苷的含量，而单独使用160 mM NaCl以及与100 nM eBL结合使用，可以促进芥蓝中芥子油苷生物合成相关基因的表达，从而增加芥子油苷的积累。芽和组合处理导致大多数芥子油苷轮廓的含量明显更高。此外，它还提高了抗坏血酸和总类胡萝卜素的含量，而没有影响总酚和抗氧化能力。
