Rhizome as a philosophical concept was developed by Gilles Deleuze and Félix Guattari in their Capitalism and Schizophrenia (1972–1980) project. It is what Deleuze calls an "image of thought", based on the botanical rhizome, that apprehends multiplicities.
Proanthocyanidins are a class of polyphenols found in many plants, such as cranberry, blueberry, and grape seeds. Chemically, they are oligomeric flavonoids. Many are oligomers of catechin and epicatechin and their gallic acid esters. More complex polyphenols, having the same polymeric building block, form the group of tannins.
Procyanidins are members of the proanthocyanidin class of flavonoids. They are oligomeric compounds, formed from catechin and epicatechin molecules. They yield cyanidin when depolymerized under oxidative conditions.
Alpinia officinarum, known as lesser galangal, is a plant in the ginger family, cultivated in Southeast Asia. It originated in China, where its name ultimately derives. It can grow 1.5 to 2 m high, with long leaves and reddish-white flowers. The rhizomes, known as galangal, are valued for their sweet spicy flavor and aromatic scent. These are used throughout Asia in curries and perfumes, and were previously used widely in Europe. They are also used as an herbal remedy.
Procyanidin B2 is a B type proanthocyanidin. Its structure is (−)-Epicatechin-(4β→8)-(−)-epicatechin.
A type proanthocyanidins are a specific type of proanthocyanidins, which are a class of flavonoid. Proanthocyanidins fall under a wide range of names in the nutritional and scientific vernacular, including oligomeric proanthocyanidins, flavonoids, polyphenols, condensed tannins, and OPCs. Proanthocyanidins were first popularized by French scientist Jacques Masquelier.
Proanthocyanidin dimers are a specific type of proanthocyanidin, which are a class of flavanoids. They are oligomers of flavan-3-ols.
Procyanidin B4 is a B type proanthocyanidin.
Procyanidin B8 is a B type proanthocyanidin.
Procyanidin A1 is an A type proanthocyanidin dimer.
Procyanidin A2 is an A type proanthocyanidin.
Afzelechin is a flavan-3-ol, a type of flavonoid. It can be found in Bergenia ligulata. It exists as at least 2 major epimers.
Selliguea feei is a fern belonging to the genus Selliguea in the family Polypodiaceae. This fern can be collected in Indonesia. The species name feei commemorates the botanist Antoine Laurent Apollinaire Fée.
Mesquitol is a flavan-3-ol, a type of flavonoid.
Condensed tannins are polymers formed by the condensation of flavans. They do not contain sugar residues.
Uncaria guianensis, the cat's claw, is a plant species in the genus Uncaria found in the Amazon biome. Other names for the plant include uña de gato, Paraguayo and vincaria.
Selliguea is a fern genus in the family Polypodiaceae. The type species is Selliguea feei.
Kaempferol-3-O-rutinoside is a bitter-tasting flavonol glycoside. It can be isolated from the rhizomes of the fern Selliguea feei.
Propelargonidins are a type of condensed tannins formed from epiafzelechin. They yield pelargonidin when depolymerized under oxidative conditions.
