Glucosinolates and its degraded products in cruciferous plants

Glucosinolates are anionic,hydrophilic and sulfur-containing secondary metabolites which are mainly found in cruciferous plants.Glucosinolates and thioglucoside glucohydrolase(myrosinase)form glucosinolate-myrosinase system in plant.Glucosinolates and myrosinase are present in the vacuoles and in the definite protosome in intact cell and tissues respectively.But when tissues and cells are damaged,my-rosinase will release and hydrolyze glucosinolates to generate degraded products,such as isothiocyanates and so on.Furthermore,recent researches have found out that isothiocyanates have the anti-cancer effects by using the inhibiting and repressing factors.
