Broccoli is also known as Brassica olaracea, Wild Cabbage, and Cauliflower. Broccoli is an edible green plant in the cabbage family, whose large flowering head is used as a vegetable. In addition to sulforaphane glucosinolate, broccoli sprouts are a superior source of Vitamin A, selenium and a good source of beta-carotene. Three-day-old broccoli sprouts contain 20 times the concentration of sulforaphane glucosinolate found in mature broccoli.
