They are known to hydrolyze into smaller phenolic compounds such as ellagic acid in vivo where one potential mechanism is hydrolysis across the mitochondrial membrane of cultured human colon cells.
32.
Muscadines also contain ellagic acid, a natural organic compound ( also found in red raspberries, strawberries and pecans ) thought to inhibit the start of cancer caused by certain chemicals.
33.
It is rich in flavonoids, such as anthocyanins, flavonols and flavanols, catechins, delphinidin 3-glucoside, cyanidin 3-glucoside, ellagic acid, and rutin; other analysis revealed the presence of gallo-and / or ellagitannins ).
34.
Blackberries rank highly among fruits for in vitro antioxidant strength, particularly because of their dense content of polyphenolic compounds, such as ellagic acid, tannins, ellagitannins, quercetin, gallic acid, anthocyanins, and cyanidins.
35.
It appears that the initial report overestimated the amount of resveratrol because it relied on a less precise method, which could not distinguish resveratrol from ellagic acid, another polyphenol found in higher concentration in muscadine grapes.
36.
A number of U . S .-based sellers of dietary supplements have received Warning Letters from the Food and Drug Administration for promoting ellagic acid with claims that violate the Federal Food, Drug, and Cosmetic Act.
37.
"U . guianensis " contains many phytochemicals ( (-)-epicatechin, alkaloid, beta-Sitosterol, campesterol, campherol, catechol, catechutannic acid, chlorogenic acid, ellagic acid, gallic acid, hyperin, oleanolic acid, rutin, stigmasterol, ursolic acid ) and proanthocyanidin B2, B type proanthocyanidins, in the root.
38.
The gallic acid dimer, ellagic acid ( M . W . 302, right ), a molecule at the core of naturally occurring phenolic compounds of varying sizes, is itself not a polyphenol by the WBSSH definition, but is by the Quideau definition.
39.
Nine compounds were isolated from the active ethylacetate fraction of the fruiting body and identified as protocatechuic acid, protocatechualdehyde, caffeic acid, ellagic acid, hispidin, davallialactone, hypholomine B, interfungins A and inoscavin A of which interfungins A is a potent inhibitor of protein glycation.
40.
For example, ellagic acid is a dimer of gallic acid and forms the class of ellagitannins, or a catechin and a gallocatechin can combine to form the red compound theaflavin, a process that also results in the large class of brown thearubigins in tea.
