Abstract Wild rocket Diplotaxis tenuifolia L. DC. belongs to the Brassicaceae family and has its origin in the Mediterranean region. The effect of conventional and integrated cultivation practices on the nutritional properties and benefits of wild rocket Diplotaxis tenuifolia L. DC. were studied. Bioactive molecules content vitamin C, quercetin, lutein, antioxidant properties and bioactivity of polyphenolic extracts from the edible part of rocket in Caco-2 cells were determined. Regarding antioxidant properties, FRAP Ferric Reducing Antioxidant Power values ranged from 4.44 ± 0.11 mmol-kg fw to 9.92 ± 0.46 mmol-kg fw for conventional rocket and from 4.13 ± 0.17 fw mmol-kg to 11.02 ± 0.45 mmol-kg fw for integrated rocket. The characteristics of wild rocket as a dietary source of antioxidants have been pointed out. Significant differences in the quality of conventional and integrated rocket have been shown, while no influence of agronomic practice on biological activity was reported. A significant accumulation of cells in G1 phase and a consequent reduction in the S and G2 + M phases were observed in Caco-2 cells treated with rocket polyphenol extract. View Full-Text
