The structural variety of the condensed tannins (proanthocyanidins) in the fruits of 16Diospyros species are reported. Eleven species contained condensed tannins mostly consisting of a mixture of catechin (CA) and gallocatechin (GCA) repeating units; the other five species did not. The GCA content in the CA-GCA total varied from 0.3% to 84.6%. The number of esterified gallic acid per one flavan repeating unit (degree of galloylation, DG) ranged from 0.01 to 0.89. The GCA content was found to be… 
Condensed Tannin Composition Analysis in Persimmon (Diospyros kaki Thunb.) Fruit by Acid Catalysis in the Presence of Excess Phloroglucinol
Persimmon (Diospyros kaki Thunb.) accumulates soluble condensed tannin (CT) in fruit which is responsible for its astringency trait. In this study, we analyzed the CT composition in persimmon fruit
Chemical Characteristics of Bark Tannins and Their Chemical and Enzymatic Conversions
In the wood industry, large quantities of wastes are generated. Bark is one of the typical wastes, and the rate of its utilization is considerably lower than that of other main wood wastes such as
Caractérisation de l’activité antioxydante des extraits de Eriobotrya japonica L
The antioxidants play a basic role in the elimination of the toxic reactive oxygen species excess. Thus, the exploitation of natural plant molecules will be very beneficial for the human health.
High molecular weight persimmon (Diospyros kaki L.) proanthocyanidin: a highly galloylated, A-linked tannin with an unusual flavonol terminal unit, myricetin.
TLDR
Thiolysis and electrochemical analysis were used to establish for the first time that persimmon tannin has a mixture of B-type and A-type linkages.
Water-insoluble condensed tannins content of young persimmon fruits-derived crude fibre relates to its bile acid-binding ability
TLDR
The results indicate that the water-insoluble condensed tannins content in young fruits of persimmon is related to its bile acid-binding ability.
Isolation and Identification of Myricitrin, an Antioxidant Flavonoid, from Daebong Persimmon Peel
TLDR
It is suggested that myricitrin was found as a major antioxidant flavonoid responsible for the strong antioxidant activities of Daebong persimmon peels.

TLDR
The original preparation, and the residue after dilute acid hydrolysis, were found to yield identifiable anthocyanidins on heating with more concentrated hydrochloric acid, while several chromatographically identified phenolics and a non-mobile but apparently less highly polymerized fraction were obtained.
