中文摘要:

      萝卜硫素是一种异硫氰酸盐, 它普遍存在于十字花科植物中, 如: 花椰菜、羽衣甘蓝、卷心菜等。由于对人体有明显的抗氧化、抗癌和抗炎等良好功效, 所以成为了一个新的健康热点。因此, 如何通过外源调控提高萝卜硫素含量与如何提高萝卜硫素的利用率成为如今的新热点。本文简要介绍了萝卜硫素的生物合成及生理功能, 综述了十字花科蔬菜在生长期可以通过喷施NaCl、肥料、植物激素、氨基酸等外源物质来调控萝卜硫素的生成量, 然后介绍了十字花科蔬菜在采后贮藏和干燥过程中萝卜硫素的变化。以期为更快地培育出富含萝卜硫素的优良品种以及如何在采后的贮藏和加工过程中调控十字花科蔬菜萝卜硫素的含量提供参考资料。

英文摘要:

      Sulforaphane is a type of isothiocyanate found in cruciferous plants such as broccoli, kale and cabbage. Because of its obvious antioxidant, anti-cancer and anti-inflammatory effects on the human body, it has become a new health hotspot. For example, how to improve the content of sulforaphane and how to improve the utilization rate of sulforaphane through exogenous regulation has become a new hot spot. This paper briefly introduced the biosynthesis and physiological functions of sulforaphane, and reviewed the production of sulforaphane in cruciferous vegetables that could be regulated by spraying exogenous substances such as NaCl, fertilizer, plant hormone and amino acid during the growth period. In addition, also introduced the changes of sulforaphane in cruciferous vegetables during postharvest storage and drying process. The study will provide insights into the cultivation of sulforaphane-rich cruciferous vegetables and how to regulate the content of sulforaphane-rich cruciferous vegetables during postharvest storage and processing.
