In the frame of the activities carried out to exploit Sicilian local cultivars of brassicas, we focused our attention on some of the potential health compounds of various local cruciferous crops. These compounds are of interest to improve the quality of the produce with the aim to develop new cultivars capable of providing functional foods able to prevent disease. In this context, we surveyed for the presence of specific glucosinolates in local cultivars of broccoli, cauliflower, kale, and in some wild species widespread in Sicily, using as control various commercial cultivars. Glucosinolate composition varied extensively among species and crops of the same species, such as cauliflower, broccoli and kale. Cultivar variation for glucosinolate profile was also observed for some crops. For example, Sicilian cultivars of cauliflower possessing colored curds displayed a high content of glucosinolates, glucoraphanin in particular, compared to white curd commercial cultivars. Also some wild species had a high content of other glucosinolates.
在为开发西西里岛当地芸苔属作物品种而开展的活动框架内，我们将注意力集中在各种当地十字花科作物的一些潜在健康化合物上。这些化合物对于提高农产品质量很重要，目的是培育出能够提供预防疾病的功能性食品的新品种。在此背景下，我们调查了西西里岛当地西兰花、花椰菜、羽衣甘蓝品种以及一些广泛分布的野生品种中特定硫代葡萄糖苷的存在情况，并将各种商业品种用作对照。硫代葡萄糖苷的组成在不同物种以及同一物种的不同作物（如花椰菜、西兰花和羽衣甘蓝）之间差异很大。在一些作物中也观察到了硫代葡萄糖苷谱的品种差异。例如，与白色花球商业品种相比，具有彩色花球的西西里岛花椰菜品种硫代葡萄糖苷含量很高，尤其是萝卜硫素。一些野生品种也含有高含量的其他硫代葡萄糖苷。
