For example, Morninga oleifera Lam has predominantly glucotropaeolin that gives rise to benzyl isothiocyanate (BITC) (Guevara et al. 1999), rocket salad has glucoerucin that gives rise to erucin as ITC product (Traka et al., 2009) and broccoli has glucoraphanin that gives rise to sulforaphane (Lai et al., 2009).
