A Comparative Study on the Nutrients, Mineral Elements, and Antioxidant Compounds in Different Types of Cruciferous Vegetables

Studies on the diversity within and among cabbage (Brassica oleracea L. var. capitata L.), cauliflower botrytis), Chinese rapa ssp. pekinensis) variants are essential for development of healthy diets. However, most studies them have been limited to a single species, with little integrated analysis between them. In this study, these species varieties is assessed by determining contents 15 major characteristic nutrients, antioxidants, minerals in 12 cabbage, 9 cauliflower, cultivated under same conditions. The results show that there significant differences compositional distributions cabbage. Cabbage has highest soluble sugars (27.73 mg·kg−1 FW), flavonoids (5.90 mg·g−1 Fe (46.90 DW). Cauliflower an ideal source protein (603.04 polyphenols (1.53 glucosinolates (25.27 μmol·g−1 Cu (4.25 rich vitamin C (0.45 FW) (K, Ca, Mg, P, Mn, Zn, at 9206.67 DW, 3297.00 3322.79 5614.78 15.36 21.87 respectively). There correlation quality, antioxidant properties, three species. principal component analysis, wide distribution high degree overlap confidence ellipse observed, indicating certain share characteristics cauliflower. These findings provide reference selecting higher nutritional value as well breeding new varieties.
