Artichoke heads Cynara scolymus) are a good source of antioxidant phenolic compounds since they contain large amounts of caffeic acid derivatives and flavonoids. The flavonoids include apigenin and luteolin glycosides. In bracts and receptacles, apigenin 5-glucoside and 7-... 

Walter s White corn plants were grown until the silks had dried. The leaves were processed and extracted in a fashion similar to teosinte. The crude extract, however, was deposited directly onto silica gel, eluted from a silica gel column as with the teosinte extract and then further purified on an open reversed phase ODS column. Luteolin glycosides were obtained in 30-50% methanohwater fractions. Further purification of small amounts for FAB-MS was achieved by thin-layer chromatography using aluminum backed silica gel plates (Whatman cat. 4420 222) with EtOAc MEK formic acid water, 5 3 1 1 as developing solvent. The compounds in the scraped bands were eluted with methanol.

In Chart 37 and Table I, structures of the flavonoids from Hepaticae and their distribution are listed. Representative flavonoids of the Hepaticae are apigenin and luteolin glycosides. Flavanones and flavonols are very rare. The most primitive liverworts, Takakia species, contain the same... 

The chemical formulae for a variety of plant phenols are given in Fig. 16.2, including examples of simpler phenols, such as cinnamic acid derivative, and of tocopherols, flavonoids, flavonoid glycosides and anthocyanidins. The flavonoids include the following subclasses flavanones (taxifolin), flavones (luteolin), flavonols (quercetin) and flavanols (catechin/epicatechin). The...
