Stryphnodendron Adstringens
''Stryphnodendron adstringens'' ( pt, barbatimão) is a species of legume in the genus ''Stryphnodendron'' found in Brazil. ''Holcocera cerradicola'' is a moth, whose larvae feed on ''S. adstringens''. Chemistry ''Stryphnodendron adstringens'' stem bark is used to produce tannins of the prorobinetinidins (flavanols oligomers containing robinetinidol) or prodelphinidins type. These are robinetinidol-(4β → 8)-epigallocatechin, robinetinidol-(4α → 8)-epigallocatechin, robinetinidol-(4β → 8)-epigallocatechin 3-O-gallate, robinetinidol-(4α → 8)-epigallocatechin 3-O-gallate, robinetinidol-(4α → 6)-gallocatechin and robinetinidol-(4α → 6)-epigallocatechin, in addition to the tentatively characterized, robinetinidol β → 6(8)gallocatechin and robinetinidol-(4α → 8)-gallocatechin.

Carl Friedrich Philipp Von Martius
Carl Friedrich Philipp (Karl Friedrich Philipp) von Martius (17 April 1794 – 13 December 1868) was a German botanist and explorer. Life Martius was born at Erlangen, the son of Prof Ernst Wilhelm Martius, court apothecary. He graduated PhD from Erlangen University in 1814, publishing as his thesis a critical catalogue of plants in the university's botanical garden. After that he continued to devote himself to botanical study, and in 1817 he and Johann Baptist von Spix were sent to Brazil by Maximilian I Joseph, the king of Bavaria. They travelled from Rio de Janeiro through several of the southern and eastern provinces of Brazil and travelled up the Amazon River to Tabatinga, as well as exploring some of its larger tributaries. On his return to Europe in 1820 Martius was appointed as the keeper of the botanic garden at Munich, including the herbarium at the Munich Botanical Collection, and in 1826 as professor of botany in the university there, and he held both offices unti ...

Frederick Vernon Coville
Frederick Vernon Coville (March 23, 1867 – January 9, 1937) was an American botanist who participated in the Death Valley Expedition (1890-1891), was honorary curator of the United States National Herbarium (1893-1937), worked at then was Chief botanist of the United States Department of Agriculture (USDA), and was the first director of the United States National Arboretum. He made contribution to economic botany and helped shape American scientific policy of the time on plant and exploration research. Biography Coville was born in 1867 in Preston, New York to bank director Joseph Addison Coville and his wife Lydia. He went to Cornell University, where he graduated with a Bachelor of Arts in 1887. He briefly taught botany before joining the USDA and participating to the Geological Survey of Arkansas as assistant botanist in 1888. He would remain with the department until his death, succeeding to George Vasey as Chief botanist in 1893, a title accompanied with that of Honorar ...

Holcocera Cerradicola
''Holcocera cerradicola'' is a moth in the family Blastobasidae. It is found in the Brazilian cerrado The ''Cerrado'' (, ) is a vast ecoregion of tropical savanna in eastern Brazil, particularly in the states of Goiás, Mato Grosso do Sul, Mato Grosso, Tocantins, Minas Gerais, and the Federal District. The core areas of the Cerrado biome are t ... in Paraná. The length of the forewings is 7.2–9.2 mm. The forewings are pale brownish grey intermixed with dark brownish-grey scales and scales tipped with white. The hindwings are translucent near the base, gradually darkening to the brown apex. The larvae feed on the fruits of '' Bauhinia holophylla'' and '' Stryphnodendron adstringens''. Etymology The species epithet, ''cerradicola'', is derived from the root ''cerrado'' (the habitat from where the type series was collected) and the Latin suffix -''cola'' (meaning inhabitant of).

Prorobinetinidin
Prorobinetidins are a type of condensed tannins formed from robinetinidol. They form robinetinidin when depolymerized under oxidative conditions. ''Mimosa'' and quebracho tannins are, according to a comparative 13C NMR study of polyflavonoids, found to be predominantly profisetinidin/prorobinetidin-type tannins. ''Stryphnodendron adstringens ''Stryphnodendron adstringens'' ( pt, barbatimão) is a species of legume in the genus ''Stryphnodendron'' found in Brazil. ''Holcocera cerradicola'' is a moth, whose larvae feed on ''S. adstringens''. Chemistry ''Stryphnodendron adstringens'' ...'' ( the barbatimão), a species of legume found in Brazil, produces prorobinetinidins in its stem bark.

Prodelphinidin
Prodelphinidin is a name for the polymeric tannins composed of gallocatechin. It yields delphinidin during depolymerisation under oxidative conditions. Natural occurrences Prodelphinidins are one of the two sorts of tannins in grape (the other being procyanidins) being produced especially in the skin of the berry. Prodelphinidins can be found in ''Cistus salviifolius''. Gallocatechin-(4→8)-catechin (prodelphinidin B3), gallocatechin-(4→8)-gallocatechin and catechin-(4→8)-gallocatechin can be found in the pomegranate peels. Prodelphinidin B-2 3'-O-gallate can be found in green tea leaves and prodelphinidin B-2 3,3'-di-O-gallate can be found in ''Myrica rubra''. Particular oligomeric prodelphinidins Prodelphinidin B3 (gallocatechin-(4α→8)-catechin) and prodelphinidin B9 (epigallocatechin-(4α→8)-catechin) can be isolated in beer. Prodelphinidin C2 (gallocatechin-(4α→8)-gallocatechin-(4α→8)-catechin) can be isolated in malt. The A-type proanthocyanidin epigal ...
