Proguibourtinidin

	Proguibourtinidin A Proguibourtinidin is a type of condensed tannins formed from guibourtinidol (leucoguibourtinidin). They yield guibourtinidin when depolymerized under oxidative conditions. They can be found in ''Guibourtia coleosperma'' (the African rosewood) or in ''Cassia abbreviata ''Cassia abbreviata'', commonly known as the sjambok pod or long-tail cassia, is a mostly tropical tree species in the genus '' Cassia'', which is native to Africa.

picture info	Cassia Abbreviata ''Cassia abbreviata'', commonly known as the sjambok pod or long-tail cassia, is a mostly tropical tree species in the genus '' Cassia'', which is native to Africa. Native distribution ''Cassia abbreviata'' is native to east, northeast, south, and west-central Africa; found in Botswana, the DRC, Kenya, Mozambique, Namibia, Somalia, South Africa (in the provinces of Limpopo and Mpumalanga), Eswatini, Tanzania, Zambia, and Zimbabwe. Uses Proguibourtinidins, a type of condensed tannins, can be found in ''C. abbreviata'' and guibourtinidol, a flavan-3ol, can be found in its heartwood. Subspecies Three subspecies are distinguished on the basis of petal size, pubescence and geographical distribution: * ''Cassia abbreviata'' subsp. ''abbreviata'' * ''Cassia abbreviata'' subsp.

picture info	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 ...

	Guibourtinidol Guibourtinidol is a flavan-3ol Flavan-3-ols (sometimes referred to as flavanols) are a subgroup of flavonoids. They are derivatives of flavans that possess a 2-phenyl-3,4-dihydro-2''H''-chromen-3-ol skeleton. Flavan-3-ols are structurally diverse and include a range of comp ....

	Guibourtia Coleosperma ''Guibourtia coleosperma'', the African rosewood (African rosewood, ambiguous), large false mopane, Rhodesian copalwood or machibi, is a species of ''Guibourtia'' in the family Fabaceae. It is a large evergreen tree (to 20 m tall) found in open woodland and dry forest, almost exclusively on Kalahari Basin, Kalahari Sand in Angola, southern Democratic Republic of Congo, Namibia, Botswana, Zambia, and Zimbabwe. The condensed tannins proguibourtinidins can be found in ''G. coleosperma''. ''G. coleosperma'' timber has a noticeable smell of menthol.
