摘要
分析了花椰菜不同器官(花球、茎、叶和根)中芥子油苷等主要生物活性物质及其抗氧化能力,发现烯丙基芥子油苷是花椰菜中主要的芥子油苷,不同器官中芥子油苷的组分与含量差异显著,根系中的总芥子油苷、总脂肪类、总芳香类以及烯丙基芥子油苷和4-甲氧基-吲哚-3-甲基芥子油苷的含量均显著高于其他器官,叶片中吲哚类芥子油苷的含量最高,花球中总芥子油苷、烯丙基芥子油苷和吲哚-3-甲基芥子油苷含量次之,茎中的总芥子油苷含量最低;叶片中的叶绿素、类胡萝卜素、维生素C和多酚含量及抗氧化能力显著高于其他器官。这些结果表明花椰菜的叶片和根系中生物活性物质含量丰富,具有进一步开发和综合利用潜力。
The bioactive compounds and their antioxidant capacity in head,stem,leave and root of mature cauliflower（Brassica oleracea L.ssp.Botrytis） plants were investigated.The results showed that sinigrin is primary glucosinolate in cauliflower.The significant differences existed in glucosinolate profile among head,stem,leave and root.The highest content of total glucosinolates,total aliphatic glucosinolates,total aromatic glucosinolates,4-methoxyglucobrassicin and sinigrin were found in root,while the highest content of indole glucosinolates was found in leave.High level of sinigrin,glucobrassicin and total glucosinolates was also observed in head,the edible parts of cauliflower,whereas the lowest content of glucosinolate was found in stem.The highest contents of chlorophyll,carotenoids,L-ascorbic acid and total phenols,as well as antioxidant capacity were detected in leave.Therefore,leave and root,which are rich in bioactive components,are the potential source for producing health-promoting products.
