Isolation of Ellagitannin Monomer and Macrocyclic Dimer from Castanopsis carlesii Leaves [PDF]

open access: yes, 2012
In a phytochemical and chemotaxonomical investigation of Castanopsis species (Fagaceae), new monomeric and dimeric ellagitannins, named carlesiins A (1) and B (2), were isolated from fresh leaves of Castanopsis carlesii along with 55 known compounds ...

Euscaphinin, a new ellagitannin dimer from Euscaphis japonica (THUNB.) KANITZ. [PDF]

open access: yes
A new ellagitannin dimer named euscaphinin was isolated from the leaves of Euscaphis japonica (THUNB.) KANITZ. The structure of this dimer was determined on the basis of spectroscopic and chemical evidence.

Production of Ellagitannin Hexahydroxydiphenoyl Ester by Spontaneous Reduction of Dehydrohexa-hydroxydiphenoyl Ester [PDF]

open access: yes
Amariin is an ellagitannin with two dehydrohexahydroxydiphenoyl (DHHDP) moieties connecting glucose 2,4- and 3,6-hydroxy groups. This tannin is predominant in the young leaves of Triadica sebifera and Carpinus japonica. However, as the leaves grow, the 3,

Structural revisions of macrocyclic ellagitannin dimers bridged by two hexahydroxydiphenoyl groups

open access: yes
Ellagitannin dimers, 1,1′;2,2′-diHHDP-diglucose and 3,3′;4,4′-diHHDP-6,6′-digalloyl-diglucose, were recently isolated from the wood of the sweet chestnut (Castanea sativa Mill.).

Influence of Wood Barrels Classified by NIRS on the Ellagitannin Content/Composition and on the Organoleptic Properties of Wine

open access: yes, 2016
Ellagitannins are extracted from oak wood during wine aging in oak barrels. This research is based on the NIRS (Oakscan) oak wood classification according to their index polyphenolic (IP) (between 21.07 and 70.15).

Clarifying the Identity of the Main Ellagitannin in the Fruit of the Strawberry, Fragaria vesca and Fragaria ananassa Duch.

open access: yes, 2012
Although the composition of strawberry fruit has been extensively studied, especially for the most abundant phenolic compounds, agrimoniin has never been univocally identified as one of the most abundant phenolic compounds in the fruit.
