Brassica definition

Brassica means any plants in the genus Brassica.

Brassica. Cells, plants, seeds, part of plants of any species of the genus Brassica cultivated for oilseed production, including but not limited to Brassica napus, Brassica juncea, Brassica rapa, Brassica carinata

Brassica napus accumulates the three flavonol derivatives (quercetin, kaempferol, and isorhamnetin) (Onyilagha et al., 2003). By using liquid chromatography-UV diode-array detection-electrospray ionization mass spectroscopy, the composition of broccoli inflorescences and characterization of a large number of hydroxycinnamic acids esters of kaempferol, quercetin and isorhamnetin glucosides were carried out. These glucosides were identified as 3-sophoroside of kaempferol, sophorotrioside-7-glucoside of quercetin and isorhamnetin sophoroside in addition to other less complex glucosides (Vallejo et al., 2004). Isorhamnetin 3,7-O-di-β-D-glucopyranoide was separated and identified from the corolla of X. xxxx flowers (Xxx et al., 2001). From X. xxxx, three flavonoids from shoots, roots and root exudates were isolated and identified: 3,5,6,7,8- pentahydroxy-4΄-methoxy flavone, 2΄,3΄,4΄,5΄,6΄-pentahydroxy chalcone and 3,5,6,7,8-pentahydroxy flavone and for the first time a flavonoid (apigenin) was elucidated from the shoots and roots (Xxxxx et al., 2004). Researchers have used both biotic and abiotic elicitors to monitor the inducible secondary metabolites in plants. Kaempferol 3-O-β-D-glucopyranoside-7- O-α-L-rhamnopyranoside, kaempferol 3,7-O-α-L-dirhamnopyranoside and quercetin glycosides were identified in methyl jasmonate treated Arabidopsis using two dimensional nuclear magnetic resonance and principal component analysis (PCA) (Xxxxxxxxxx et al., 2006). UV-B radiation was used in two cultivars of B. napus to enhance the overall amounts of soluble flavonoids. Quercetin glucosides and kaempferol increased by 150% in the atrazin sensitive cultivar compared to control plants and increased by 70% in the atrazin tolerant cultivar compared to control plants from B. napus (Xxxxxx et al., 1998).
