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'' 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.

Condensed Tannin
Condensed tannins (proanthocyanidins, polyflavonoid tannins, catechol-type tannins, pyrocatecollic type tannins, non-hydrolyzable tannins or flavolans) are polymers formed by the condensation of flavans. They do not contain sugar residues. They are called proanthocyanidins as they yield anthocyanidins when depolymerized under oxidative conditions. Different types of condensed tannins exist, such as the procyanidins, propelargonidins, prodelphinidins, profisetinidins, proteracacinidins, proguibourtinidins or prorobinetidins. All of the above are formed from flavan-3-ols, but flavan-3,4-diols, called (leucoanthocyanidin) also form condensed tannin oligomers, e.g. leuco-fisetinidin form profisetinidin, and flavan-4-ols form condensed tannins, e.g. 3',4',5,7-flavan-4-ol form proluteolinidin (luteoforolor). One particular type of condensed tannin, found in grape, are procyanidins, which are polymers of 2 to 50 (or more) catechin units joined by carbon-carbon bonds. These are not ...

Mimosa
''Mimosa'' is a genus of about 590 species of herbs and shrubs, in the mimosoid clade of the legume family Fabaceae. The generic name is derived from the Greek word (''mimos''), an "actor" or "mime", and the feminine suffix -''osa'', "resembling", suggesting its 'sensitive leaves' which seem to 'mimic conscious life'. Two species in the genus are especially notable. One is ''Mimosa pudica'', commonly known as touch-me-not, which folds its leaves when touched or exposed to heat. It is native to southern Central and South America but is widely cultivated elsewhere for its curiosity value, both as a houseplant in temperate areas, and outdoors in the tropics. Outdoor cultivation has led to weedy invasion in some areas, notably Hawaii. The other is ''Mimosa tenuiflora'', which is best known for its use in shamanic ayahuasca brews due to the psychedelic drug dimethyltryptamine found in its root bark. Taxonomy The taxonomy of the genus ''Mimosa'' has gone through several periods of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quebracho Tannin
Quebracho is a common name in Spanish to describe very hard (density 0.9–1.3) wood tree species. The etymology of the name derived from ''quiebrahacha'', or ''quebrar hacha'', meaning "axe-breaker". Species There are at least three similar commercially important tree species that grow in the Gran Chaco region of South America. * the quebracho ** ''Schinopsis lorentzii'' (Syn.: ''Schinopsis marginata'' Engl., ''Schinopsis haenkeana'' Engl.); of the family Anacardiaceae; North Argentina, Paraguay and Bolivia; (the red quebracho, quebracho), ''quebracho-colorado santiagueño'', ''red quebracho santiagueño'', ''quebracho santiagueño'' (also known as ''quebracho cor(o)nillo'', ''cor(o)nillo'', ''quebracho macho'', ''quebracho negro'' or ''moro'', ''quebracho rojo'', ''quebracho bolí'', ''horco quebracho'', ''quebracho serrano'', ''quebracho montano'', ''quebracho crespo'', ''quebracho del cerro'', ''quebracho colorado de las sierras'' o ''del cerro'' and ''quebracho cordobés ...
