A related glucosinolate glucoraphanin is found in broccoli, and is associated with beneficial medicinal properties of this vegetable. This is hydrolysed to the isothiocyanate sulforaphane, which is believed to induce carcinogen-detoxifying enzyme systems. 

State produces 95% of the broccoli grown commercially in the United States ( ) and it has been reported that residues of broccoli are phytotoxic and inhibit the establishment of other crops ( ). Both species, campestris and oleracea var. italica, belong to the Brassicaceae, which contain as a characteristic chemical compounds the glucosinolates , . Species from the Brassicaceae family have... 

The water-soluble extracts of wild mustard and broccoli plants were species specific, as shown by the results obtained by other authors (22, 31, 32). The greater insensitivity of crucifers is apparently related to the presence of specific myrosinases which are capable of transforming the breakdown products of the glucosinolates (33). 

Isothiocyanates ( mustard oils ) and their glucosinolate precursors are widely distributed in higher plants, especially among cruciferous vegetables, and it has been established recently that sulforaphane, found in various species and particularly in broccoli, is the major source of their anticarcinogenic action [181].

Figure 7.2 Distribution pattern of major glucosinolates in various vegetables belonging to Brassica oleracea. Fresh samples of the edible part of the vegetable were freeze-dried and analyzed for glucosinolate content by previously published methods. Data are mean pmols glucosinolate/g dry weight vegetable 50 varieties of broccoli, 4 varieties of Brussels sprouts, 6 varieties of cabbage, 3 varieties of cauliflower, and 2 varieties of kale.
