摘　　要：选择典型的芥蓝品种为材料,分析不同器官可溶性固形物、还原糖、可溶性蛋白、叶绿素、类胡萝卜素,维生素C和总多酚含量,以及抗氧化能力、芥子油苷组分和含量的差异。结果表明:芥蓝不同器官间营养成分的含量差异显著,总体上花序中的总多酚、维生素C和可溶性固形物含量显著高于其它器官;叶片中的叶绿素、类胡萝卜素、可溶性蛋白和抗氧化能力均显著高于其它器官;根系中的芥子油苷,特别是苯乙基芥子油苷和4–甲基硫丁基芥子油苷的含量均显著高于其它器官。芥蓝不同品种间产品器官花薹的营养价值差异显著,如‘JL-02’的总多酚含量和抗氧化能力明显高于其它品种,‘登峰中迟’的4–甲基硫氧丁基芥子油苷和总芥子油苷含量明显高于其它品种。The variation of the contents of soluble solids,reducing sugars,soluble proteins,chlorophyll,carotenoids,vitamin C,and total phenols,as well as antioxidant capacities and glucosinolate profiles among different organs were investigated using Chinese kale（Brassica alboglabra Bailey）of typical varieties as material. The results showed that the contents of nutrients exhibited remarkable differences among different organs. In general,the highest contents of total phenols,vitamin C and soluble solids were found in inflorescences,and the significant differences existed between inflorescences and other organs. The contents of chlorophyll,carotenoids,soluble proteins and antioxidant capacities in leaves were remarkably higher than those in other organs. The roots contained markedly higher concentrations of glucosinolates,especially gluconasturtiin and glucoerucin,than those in other organs. Great differences in the nutrition value of bolting stem,the edible part of Chinese kale were observed among different varieties. JL-02 had the highest amounts of total phenols and antioxidant capacities. The significantly higher level of glucoraphanin and total glucosinolates was found in Dengfengzhongchi.
