Ellagic Acid
Ellagic acid is a polyphenol found in numerous fruits and vegetables. It is the dilactone of hexahydroxydiphenic acid. Name The name comes from the French term ''acide ellagique'', from the word ''galle'' spelled backwards because it can be obtained from ''noix de galle'' ( galls), and to distinguish it from ''acide gallique'' (gallic acid). The molecule structure resembles to that of two gallic acid molecules being assembled "head to tail" and bound together by a C–C bond (as in biphenyl, or in diphenic acid) and two lactone links (cyclic carboxylic esters). Metabolism Biosynthesis Plants produce ellagic acid from hydrolysis of tannins such as ellagitannin and geraniin. Biodegradation Urolithins are gut flora human metabolites of dietary ellagic acid derivatives. Ellagic acid has low bioavailability, with 90% remaining unabsorbed from the intestines until metabolized by microflora to the more bioavailable urolintins.

Rutin
Rutin, also called rutoside, quercetin-3-O-rutinoside and sophorin, is the glycoside combining the flavonol quercetin and the disaccharide rutinose (α-L-rhamnopyranosyl-(1→6)-β-D-glucopyranose). It is a flavonoid found in a wide variety of plants, including citrus. Occurrences Rutin is one of the phenolic compounds found in the invasive plant species, '' Carpobrotus edulis''. Its name comes from the name of '' Ruta graveolens'', a plant that also contains rutin. Various citrus fruit peels contain 32 to 49 mg/g of flavonoids expressed as rutin equivalents. Citrus leaves contain rutin at concentrations of 11 and 7 g/kg in orange and lime trees, respectively. In 2021, Samoan researchers identified rutin in the native plant, ''matalafi'' (''Psychotria insularum''). Metabolism The enzyme quercitrinase found in ''Aspergillus flavus'' is in the rutin catabolic pathway. In food Rutin is a citrus flavonoid glycoside found in many plants, including buckwheat, the leaves and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Iso-orientin
Isoorientin (or homoorientin) is a flavone, a chemical flavonoid-like compound. It is the luteolin-6-C-glucoside. Bioassay-directed fractionation techniques led to isolation of isoorientin as the main hypoglycaemic component in ''Gentiana olivieri''. Studies also showed that isoorientin is a potential neuroprotective compound against Alzheimer's disease.
