Sulforaphane (sulphoraphane in British English) is a compound within the isothiocyanate group of organosulfur compounds. It is obtained from cruciferous vegetables such as broccoli, Brussels sprouts, and cabbages. It is produced when the enzyme myrosinase transforms glucoraphanin, a glucosinolate, into sulforaphane upon damage to the plant (such as from chewing), which allows the two compounds to mix and react. Young sprouts of broccoli and cauliflower are particularly rich in glucoraphanin.

glucoraphanin, glucosinolate precursor to sulforaphane

Occurrence and isolation[edit]

Sulforaphane was identified in broccoli sprouts, which, of the cruciferous vegetables, have the highest concentration of sulforaphane.[1] It is also found in Brussels sprout, cabbage, cauliflower, bok choy, kale, collards, Chinese broccoli, broccoli raab, kohlrabi, mustard, turnip, radish, arugula, and watercress.


Although there is basic research on how sulforaphane may affect mechanisms in vivo,[2][3] there is no high-quality evidence to date for its efficacy against human diseases.[4]
