食用甘蓝类植物与降低人类某些癌症的发病率有关，而这与这些蔬菜中存在的芥子油苷有关。种子成熟后，一些十字花科植物的芽中含有最高浓度的这些化合物，因此是用于化学保护的硫代葡萄糖苷的良好来源。本实验采用高效液相色谱法测定了5个甘蓝品种（白甘蓝、红甘蓝、皱叶甘蓝、西兰花和花椰菜）成熟种子和芽（苗）中芥子油苷的含量和分布。各个芥子油苷的类型和浓度根据甘蓝的品种、它们存在的植物部位以及种子的发芽期而变化。在整个发芽期间，烷基芥子油苷的浓度下降，而吲哚-3-基甲基芥子油苷的浓度增加。根在四天和七天的芽中具有最高浓度的芥子油苷，而在这两个发芽时间，子叶具有最高浓度的烷硫基芥子油苷和烷基亚磺酰芥子油苷。 (C) 2007 Elsevier B.V. 保留所有权利。
Consumption of plants of the species Brassica oleracea is related to a decreased incidence of certain cancer forms in humans, and this has been linked to the presence of glucosinolates in those vegetables. After ripe seeds, sprouts of some brassicaceous plants contain the highest concentration of these compounds and are therefore a good source of glucosinolates for chemoprotection. In the present experiments, the content and distribution of glucosinolates was determined in ripe seeds and sprouts (seedlings) of five varieties of B. oleracea (white cabbage, red cabbage, Savoy cabbage, broccoli and cauliflower) by high performance liquid chromatography. The type and concentration of individual glucosinolates varied according to variety of B. oleracea, plant parts in which they occurred and the sprouting period of the seed. Concentration of alkyl glucosinolates decreased whereas that of indol-3-ylmethylglucosinolates increased throughout the sprouting period. Roots had the highest glucosinolate concentration in four and seven day old sprouts whereas at both sprouting times, cotyledons had the highest concentration of alkylthio- and alkylsulphinylglucosinolates.
