Sodium borohydride reduction of anthocyanidins

Phytochemistry, 1972
Abstract The reduction of anthocyanidins with NaBH 4 in EtOH or MeOH produces inter alia racemates of epicatechins. Thus, the (±) racemates of 3′,5′-di- O -methylepigallocatechin, 3′- O -methylepigallocatechin, and 3′- O -methylepicatechin have been identified as the reduction products of malvidin, petunidin, and peonidin, respectively, by their ...

Some characteristics of the additional anthocyanidins formed during conversion of leucoanthocyanidins into anthocyanidins

Phytochemistry, 1969
Abstract During the conversion of leucoanthocyanidins into anthocyanidins with alcoholic HCl small amounts of additional anthocyanidins are formed, which appear to be simple ethers of the anthocyanidins and the alcohol used in the medium. The chromatographic characteristics of such derivatives produced from different leucoanthocyanidins have been ...

Anthocyanidins and related compounds—XII

Tetrahedron, 1968
Abstract Crystalline phloroglucinol and resorcinol condensation products with 5,7,3′,4′-tetramethoxyflavan-3,4-diol have been prepared. The structures of these products have been confirmed by extensive analytical and nuclear magnetic resonance spectral measurements.

Zur Kenntnis der Pro‐anthocyanidine

Chemische Berichte, 1961
AbstractEs werden monomolekulare, dimere und polymere Pro‐anthocyanidine1 beschrieben. Aus den Früchten des Weißdorns (Crataegus oxyacantha) läßt sich (−)‐Epi‐catechin und ein dimeres Pro‐cyanidin (XIV oder XV) isolieren, das beim kurzen Erwärmen mit verdünnter Säure in Epi‐catechin und Cyanidin zerfällt2.

A DFT investigation of anthocyanidins

Chemical Physics Letters, 2005
Abstract A theoretical analysis of anthocyanidins, a class of natural plant pigments, has been conducted using density functional theory at the B3LYP/6-31G(d) level. It is found that these compounds are non-planar, with the 2-phenyl ring twisted relative to the benzopyrylium rings.
