The purpose of this study was to clearly understand the health-promoting potentials of broccoli seeds and sprouts according to identify their representative bioactive compounds and antioxidant activities in six varieties. Sulforaphane (SF) extraction was firstly optimized from seeds and sprouts. Then SF extracted under optimized conditions from seeds and sprouts were compared. Most varieties obtained the maximum SF, total phenolic (TP) and flavonoid (TF) contents in sprouts on day 3. SF contents in sprouts were 46%-97% of seeds, whereas TP and TF contents in sprouts were 1.12-3.58 times higher than seeds among varieties. After in vitro digestion, broccoli sprouts from MNL variety kept considerable SF, TF, and TP contents, as well as antioxidant capacities, with all values higher than seeds. Compared with seeds, sprouts after 3 days germination were also recommended as raw materials of functional foods that possess high health-promoting potential.

萝卜硫素及其在不同品种西兰花种子和新芽中的抗氧化作用。

这项研究的目的是通过识别六个品种中具有代表性的生物活性化合物和抗氧化活性，从而清楚地了解西兰花种子和新芽的健康促进潜力。首先从种子和新芽中优化了萝卜硫素（SF）的提取。然后比较了在最佳条件下从种子和芽中提取的SF。大多数品种在第3天在芽中获得最大的SF，总酚（TP）和类黄酮（TF）含量。芽中SF含量是种子的46％-97％，而芽中TP和TF含量高1.12-3.58倍比品种间的种子要多。经过体外消化后，来自MNL品种的西兰花芽苗菜具有相当的SF，TF和TP含量以及抗氧化能力，所有值均高于种子。与种子相比
