Which specific Isothiocyanate (ITC) is present in notably high concentrations within genuine wasabi that is frequently cited as the source of its remarkable potential?

6-methylsulfinylhexyl isothiocyanate (6-MSITC)

While many cruciferous vegetables share sulfur-containing organic compounds (ITCs) that give them sharp flavors, *Wasabia japonica* is particularly noted for containing very high concentrations of a specific ITC called 6-methylsulfinylhexyl isothiocyanate, often abbreviated as 6-MSITC. This specific compound is the primary focus of specialized research exploring the potent protective qualities attributed to true wasabi, especially concerning detoxification and anti-cancer mechanisms. Glucoraphanin is a precursor, and sulforaphane is a related ITC more commonly associated with broccoli, setting 6-MSITC apart as the signature active component of real wasabi.
