Brassicaceae (Brassicaceae) is one of the families belonging to the order Brassicaceae. It used to be called Cruciferae because its four petals look like a cross. In the APG plant classification system, the family names of all plants have been changed to those derived from the typical genus, so they are derived from the genus Brassica, but the old scientific name is also accepted as a conserved name and is the latest. In many books, the new name and the reserved name are written together. It features cruciform petals and elongated (flat fan-shaped, depending on the species) silique. Includes those used as vegetables or spices, such as wasabi, cabbage, and radish. Arabidopsis is also famous as a model organism. Brassicaceae is closely related to Cleomaceae and was also included in the Brassicaceae (provisionally) in the APG plant classification system (up to the second edition) because the detailed relationships within the group were unknown. In the APG plant classification system 3rd edition, it is separated again.


There are special cells called "myrosin cells" in the phloem, and it is also a major feature that soft cells contain mustard oil glycosides (including closely related Cleomaceae and Moringa). When the plant is damaged, the intracellular enzyme (myrosinase) hydrolyzes the glycoside to release allyl isothiocyanate. This substance is a pungent component peculiar to mustard, wasabi, grated radish, etc., and is a means to protect against feeding damage by herbivores such as insects. Brassicaceae vegetables are said to have a cancer-preventing effect, both because of the effect of brassicaceae isothiocyanate and because the isothiocyanate derivative works on enzymes that have the effect of detoxifying by conjugation reaction in the liver. It is said. Sulforaphane is a kind of isothiocyanate and is contained in broccoli among Brassicaceae vegetables, and is said to have a cancer-preventing effect. No association with breast cancer was observed in total vegetable and fruit intake, but it has been reported that premenopausal women are less likely to develop breast cancer as the intake of "Brassicaceae vegetables" is higher. Many Brassicaceae plants have antimutagenicity. It contains S-methylcysteine ​​sulfoxide and changes to dimethyl disulfide as a result of a chemical reaction in the intestines of ruminants, causing hemolytic anemia in cattle and sheep. In the past, Brassicaceae plants belonged to two groups in the pyramid of the Designer Foods Project, and although they belong to the lowest of the two groups, they were positioned as foodstuffs with cancer-preventing effects.
