Flavone glycosides often occur as acylated derivatives either with aliphatic or aromatic acids. Hydroxy-cinnamic acid derivatives are the most frequent in nature and MS fragmentations of these types of compounds show ions produced by the loss of 146,162,176, or 206 m.u., corresponding to the losses of the acyl residues />-coumaroyl, caffeoyl, femloyl, or sinapoyl, respectively. Brassicaceae species are rich in flavonoid glycosides acylated with hydroxyl-cinnamic derivatives, and most of them... 

Erucic acid is generally excluded from the sn-2 position of seed oil triglycerides (TAGs)of Brassicacea species. Stereospecific analyses ofBrassica juncea, B. napus, B. oleracea, B. rapa, Crambe abyssinica, Lunaria annua, Sinapis alba, and other wild Cruciferae (1-4) have not yet detected significant amounts of erucic acid in the sn-2 position.

In some cases, the anionic POs adsorbed on chitin have similar antigenic determinants, but the plants belonging to different families - and even members of the same family - could have polysaccharide-specific POs with different structures. Thus, the majority of investigated species had anionic chitin-specific peroxidises, and these isoforms from potato Solcmaceae) and horseradish Brassicaceae) formed lines of precipitation with antibodies to wheat chitin-bound PO but not to anionic isoPO (Maksimov et al., 2000). However, protein extracts from several plants of Brassicaceae, Cucurhitaceae and Fahaceae formed precipitate with both the chitin-specific and anionic PO of wheat (Fig. 3). It was foimd that the greatest homology showed in plants and formed precipitation lines with the anionic PO of wheat (Tab. 2). 

It is impossible to reveal the botanical species from which the seed oil used in the examined lamps was actually produced, e.g. to say whether the oil came from radish as reported by Pliny or from another Brassicaceae plant such as rapeseed. However, the detection of the characteristic markers in lamps from Antinoe, one of the main urban centres of Roman Egypt, represents a chemical confirmation of the widespread use of cmciferous oil at that time, and is consistent with ancient documents [61,62]. This identification is... 

Flavone synthase (FNS EC 1.14.11.22) introduces a double bond between C2 and C3 of a flavanone to produce the corresponding flavone. This activity was initially identified in parsley cell suspension cultures and subsequently shown to be encoded by a 2-oxoglutarate-dependent dioxygenase [67, 78, 79], This enzyme, now known as FNS-I, appears to have very limited distribution. To date, it has only been identified in the Apiaceae family (Umbellifers). The more widely occurring FNS-II (CYP93B) was initially identified from snapdragon (Antirrhinum majus) flowers [80] and was subsequently shown to be a P450 enzyme. FNS-I, FNS-II, and the various roles flavones play in plant species have recently been reviewed by Martens and Mithofer [81], Subsequent to this review, Yu et al. [82] demonstrated that the characteristic lack of natural accumulation of flavones in Brassicaceae could not be overcome in A. thaliana even by overexpression of recombinant parsley FNS-I. 

State produces 95% of the broccoli grown commercially in the United States ( ) and it has been reported that residues of broccoli are phytotoxic and inhibit the establishment of other crops ( ). Both species, campestris and oleracea var. italica, belong to the Brassicaceae, which contain as a characteristic chemical compounds the glucosinolates , . Species from the Brassicaceae family have...

A major proportion of the glucosinolate hydrolysis products formed upon myrosinase cleavage in some plants are nitriles. In vitro, nitrile formation associated with myrosinase-catalyzed hydrolysis is enhanced at low pH (pH<3) and in the presence of ferrous ions. In vivo, protein factors in addition to myrosinase may be responsible for nitrile formation. If the glucosinolate side chain has a terminal double bond, the sulfur released from the thioglucosidic bond may be captured by the double bond and an epithionitrile is formed.9 This reaction takes place only in plants that possess a protein factor known as epithiospecifier protein (ESP). ESP activities have been identified in several species of the Brassicaceae and shown to influence the outcome of the myrosinase-catalvzed hydrolysis reaction although they have no hydrolytic activity by themselves.10 12 The mechanism by which ESPs promote epithionitrile formation is not known.
