Cytotoxic ellagitannins from Reaumuria vermiculata
Fitoterapia, 2012Three ellagitannins and one disulfated flavonol were isolated from the aerial parts of Reaumuria vermiculata L. Besides that, 16 known compounds were characterized as well. The structures of all compounds were elucidated on the basis of spectroscopic data including 1D and 2D NMR and ESI HR-FTMS. The in vivo antioxidant activity using the oxygen radical

The bioavailability of raspberry anthocyanins and ellagitannins in rats
Molecular Nutrition & Food Research, 2007AbstractThe fate of anthocyanins and ellagitannins in rats was monitored following ingestion of raspberry juice. After 1 h low nM concentrations of unmetabolised anthocyanins were present in plasma but these declined by 2 h and after 4 h they were no longer detectable.

Ellagitannins, ellagic acid and vascular health
Molecular Aspects of Medicine, 2010Hydrolysable tannins are phenolic phytochemicals that show high antioxidant and free-radical scavenging activities. For this reason their potential effects preventing oxidative related diseases, such as cardiovascular diseases, have been largely studied.

Detection and determination of ellagitannins
Phytochemistry, 1972Abstract Ellagic acid combined in the form of esters of hexahydroxydiphenic acid (HHDP) can be quantitatively determined by taking advantage of the formation of a coloured product with nitrous acid. Under specified conditions, monoesters with glucose have molecular absorption coefficients between 2150 and 2300 at 600 nm.

Highly Oxidized Ellagitannins and Their Biological Activity
1999Polyphenols such as flavonoids and tannins in medicinal plants, foods, and beverages are attracting considerable attention in human health care because of their biologically multifunctional properties. These properties include antioxidant activity due to radical scavenging action and anti-HIV, antitumor activities, and inhibitory effects on various ...

Journal of the American Chemical Society, 1994
Tellimagrandin I was synthesized by two different biogenetically patterned routes. One route featured diastereoselective galloyl ester coupling between the O(4) and O(6) galloyl moieties in a glucose-derived substrate bearing additional protected galloyl groups on 0(2) and 0(3).
