【摘要】 分析了青花菜花球、茎、叶和根中生物活性物质和营养成分组分与含量的差异。结果发现,花球中的总脂肪类、总吲哚类、总芥子油苷以及抗癌活性最强的4-甲基硫氧丁基芥子油苷的含量均显著高于其它器官,根系中苯乙基芥子油苷、4-甲基硫丁基芥子油苷和4-甲氧基-吲哚-3-甲基芥子油苷含量显著高于其它器官;花球中的可溶性蛋白、还原糖和可溶性固形物含量显著高于其它器官;叶片中的多酚、维生素C、叶绿素和类胡萝卜素含量以及抗氧化能力显著高于其它器官。叶片和根系生物活性物质含量丰富,可加以综合利用。更多还原

【Abstract】 The present study investigated the contents of bioactive compounds and nutrients,as well as antioxidant capacities in heads,stems,leaves and roots of mature broccoli(Brassica oleracea var.italica Planck)plants.The results showed that the heads had the highest amounts of aliphatic glucosinolates,indole glucosinolates,total glucosinolates and glucoraphanin,which was one of the most potential anticarcinogenic glucosinolate identified thus far.The contents of gluconasturtiin,glucoerucin and 4-methoxyglucobrassicin in the roots were remarkably higher than those in the other organs.As for the nutrients,the broccoli heads contained markedly higher concentrations of soluble proteins,reducing sugars and soluble solids than those in the leaves,roots and stems.The highest contents of total phenols,L-ascorbic acid,chlorophyll and carotenoids,as well as antioxidant capacities were observed in leaves,and the significant differences existed between leaves and other organs.The leaves and roots of broccoli,which are rich sources of bioactive components,have great potential for producing health-promoting products and biological pesticides as raw materials.更多还原
