Phenolics from Maytenus senegalensis

Two new methylated flavan-3-ol glucosides and a methylated proanthocyanidin were isolated from the MeOH extract of the stem-bark of Maytenus senegalensis, together with five known compounds. The structures of the new compounds were determined as: (-)-4'-m

Oligomeric flavanoids. Part 27. Interflavanyl bond formation in procyanidins under neutral conditions

Dimethyl(methylthio)sulfonium tetrafluoroborate (DMTSF) and silver tetrafluoroborate (AgBF4) activate the C4-S bond in the 4-thioethers of flavan-3-ols toward carbon nucleophiles to permit formation of the interflavanyl bond in procyanidins under neutral conditions.

Proanthocyanidins from Lotus Corniculatus

The chemical structure of the purified proanthocyanidin polymers of Lotus corniculatus was analysed by 13CNMR and by mild acid catalysed degradation in the presence of excess of phloroglucinol. The NMR data showed that the polymer was partially glycosidated with a number average Mr in the range 1800-2100 (six to seven flavanoid units). The products from phloroglucinol scission reaction indicated the extender flavan units to consist mostly of epicatechin (67%) and epigallocatechin (30%), with minor amounts of catechin and epiafzelechin units, which were linked together predominantly by C-4/C-8 interflavanoid bonds. The polymer chains were terminated mostly by catechin (83%) and, to a lesser extent, by epicatechin (16%). Copyright
