以西兰花、甘蓝、白色萝卜和红萝卜的7日龄种芽为材料，研究了低温贮藏对硫代葡萄糖甙含量的影响。鉴定出的主要硫代葡萄糖酸苷是萝卜苷和葡萄糖芥子素（西兰花、甘蓝和萝卜中）、葡萄糖黄苷（西兰花和甘蓝中）以及萝卜苷和葡萄糖脱氢芥子素（白色萝卜中）。一般来说，芽菜在4 ℃下储存3周期间，个别硫代葡萄糖苷浓度没有显着变化。火箭是一个例外，它分别在1周和2周后显示出葡萄糖芥酸和萝卜硫苷的显著下降。这些初步结果表明，由于西兰花，萝卜和甘蓝芽中的硫代葡萄糖苷没有显著损失，这些芽可以在家用冷藏条件下储存，而不会显著损失潜在的抗癌化合物。另一方面，如果要保持硫代葡萄糖甙水平，则应在购买后不久食用火箭芽。(c)2006 Elsevier B.V.保留所有权利。
The effect of cold storage on glucosinolate concentration was examined in 7-day-old seed-sprouts of broccoli, kohl rabi, white radish and rocket. Principal glucosinolates identified were glucoraphanin and glucoerucin (in broccoli, kohl rabi and rocket), glucoiberin (in broccoli and kohl rabi), and glucoraphenin and glucodehydroerucin (in white radish). Generally, sprouts showed no significant changes in individual glucosinolate concentrations during storage at 4 degrees C for 3 weeks. The exception to this was rocket, which showed a significant decline in glucoerucin and glucoraphanin after 1 and 2 weeks, respectively. These preliminary results indicate that as there is no significant loss of glucosinolates in broccoli, radish and kohl rabi sprouts, these sprouts may be stored under domestic refrigeration conditions without significant loss of potential anti-cancer compounds. Rocket sprouts, on the other hand, should be consumed soon after purchase if glucosinolate levels are to be maintained. (c) 2006 Elsevier B.V. All rights reserved.
