Über Kondensationsreaktionen der Catechine, III. Die Selbstkondensation von (+)‐Catechin

Justus Liebigs Annalen der Chemie, 1961
AbstractAus (+)‐Catechin entstehen in wäßrig‐saurem Medium durch Epimerisierung und Kondensation im Anfangsstadium (+)‐Epicatechin und zwei epimere Kondensationsdimere, von denen bislang eines in kristallisierter Form isoliert wurde. Es ist dies der erste kristallisierte Catechingerbstoff.

Catechin‐Resorcin‐Kondensate

Justus Liebigs Annalen der Chemie, 1965
AbstractDie methylierten Kondensationsprodukte, die aus Tetramethyl‐(+)‐catechin (I) und Resorcin unter der Einwirkung von Säuren entstehen, besitzen die Konstitution II und V. Die Konstitution von II wird durch Analysen, IR‐ und NMR‐Spektren (von II und seinen Derivaten III und IV) bewiesen. Die Konstitution von V wird durch Massenspektroskopie, durch

(−)-Catechin glycosides from Ulmus davidiana

Archives of Pharmacal Research, 2013
Extensive chromatographic separation of the n-BuOH soluble fraction obtained from the stem and root barks of U. davidiana resulted in five hitherto unknown compounds together with a known one (-)-catechin 1. Structures of the five compounds were elucidated by chemical and spectroscopic analyses, to be (-)-catechin-7-O-gallate-5-O-(5″″-trans-caffeoyl)-β-

Black Wattle Catechin

Nature, 1958
CONDENSED tannins present in black wattle or commercial ‘mimosa’ extracts from the bark of Acacia mollissima show absorption behaviour (λmax. = 203 and 280 mµ) in the ultra-violet spectrum1, which is typical of the natural catechins and flavan-3.4-diols2 and also of their constituent phenols.
