Prodelphinidin is a name for the polymeric tannins composed of gallocatechin.〔Porter, 1992〕〔Prodelphinidin polymers: definition of structural units. Lai Yeap Foo and Lawrence J. Porter. J. Chem. Soc., Perkin Trans. 1, 1978, pp. 1186-1190, 〕 It yields delphinidin during depolymerisation under oxidative conditions. Prodelphinidins can be found in ''Cistus salviifolius''.〔Flavan-3-ols, prodelphinidins and further polyphenols from Cistus salvifolius. Andreas Danne, Frank Petereit and Adolf Nahrstedt, Phytochemistry, Volume 37, Issue 2, 1994, Pages 533–538, 〕 Gallocatechin-(4→8)-catechin (prodelphinidin B3), gallocatechin-(4→8)-gallocatechin and catechin-(4→8)-gallocatechin can be found in the pomegranate peels.〔Antioxidant properties of gallocatechin and prodelphinidins from pomegranate peel.

C and Williamson G, Redox Report, February 2002, Volume 7, Number 1, pages 41-46, 〕 Prodelphinidin B-2 3'-O-gallate can be found in green tea leavesand prodelphinidin B-2 3,3'-di-O-gallate can be found in ''Myrica rubra''. Prodelphinidin B3 (gallocatechin-(4α→8)-catechin) and prodelphinidin B9 (epigallocatechin-(4α→8)-catechin) can be isolated in beer.〔Phenolic Compounds in Beer. Clarissa Gerhäuser and Hans Becker, Beer in Health and Disease Prevention, 2009 ((article ))〕 Prodelphinidin C2 (gallocatechin-(4α→8)-gallocatechin-(4α→8)-catechin) can be isolated in malt. The A-type proanthocyanidin epigallocatechin-(2β→7,4β→8)-epicatechin can be found in the leaves of ''Dioclea lasiophylla'', == See also == * Crofelemer, a complex mixture of procyanidins and prodelphinidins from the latex of the South American tree ''Croton lechleri'' (locally called Sangre de Grado or Sangre de Drago) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Prodelphinidin」の詳細全文を読む スポンサード リンク
