Health-related compound profile of Brussels sprouts plants (Brassica oleracea var. gemmifera)

Glucosinolates, vitamin C, carotenoids and vitamin K1 concentrations were determined in different parts of the Brussels sprouts buds (outer leaves, middle leaves and core) and the Brussels sprouts plant (stem, buds, petioles and leaves). The outer leaves of the Brussels sprouts buds contained approximate to 26 approximate to 959 carotenoids and vitamin K1, respectively, compared to the core. Total glucosinolates concentrations were evenly distributed, although their profile was different. Regarding the Brussels sprouts plant, glucosinolates were mainly present in the stem (153 +/- 21 mg/ 100 g fresh weight) and the buds (88 +/- 8 mg/100 g fresh weight). Carotenoids and vitamin K1 were distinctly more present in the leaves (24 +/- 1 mg/ 100 g fresh weight and 0.62 +/- 0.07 mg/ 100 g fresh weight, respectively). The buds contained 44 to 5085 +/- 3 mg/ 100 g fresh weight) than the other parts of the Brussels sprouts plant.
