Crucifers, i.e. Brassicaceae, constitute a large family of plants — mustard, cabbage, radish, turnip, cress, rocket, wasabi, oilseed rape, etc. — that are routinely used in human and animal nutrition but also as pharmaceuticals, cosmetics and dyes. From a phytochemical point of view, this plant family is characterized by sulfur-containing natural products called glucosinolates (GLs). When the plant cells are damaged, glucosinolates are degraded by myrosinase, an enzyme present in separate cell compartments, thus generating diverse molecules. Isothiocyanates are mainly formed but nitriles, thiocyanates and oxazolidinethiones can also be produced, depending on the structure of the starting glucosinolate (GL) and physicochemical conditions of hydrolysis. We present some prospects for the utilization of cruciferous plant extracts. We address some of the achievements, mainly highlighting the bioactivities of isothiocyanates and glucosinolates.
