Glucosinolates represent a group of phytochemicals found in 15 botanical families of the order of Capparales and are very abundant in Brassicaceae . A very different profile of glucosinolates may be found in different broccoli extracts . In a recent paper, the most abundant glucosinolates found in different broccoli samples were glucobrassicin and neoglucobrassicin, followed by glucoraphanin. Interestingly, glucoraphanin, which is one of the most representative glucosinolates in broccoli, was completely absent in the ecotype “Friariello” from the Campania region . Also, the content of glucosinolates may be deeply different in different broccoli varieties. For example, analyses conducted on a collection of 113 varieties of turnip greens (Brassica rapa L.), cultivated in two different sites in Spain, showed glucosinolates contents ranging from 12 to 70 µmol/g DW at one site, and from 7 to 60 μmol/g DW at the other site .
