    A-type proanthocyanidins from peanut skins
    摘要:
    Six A-type proanthocyanidins were isolated from the water-soluble fraction of peanut skins. On the basis of spectral data, reductive cleavage with sodium cyanoborohydride, and chiral HPLC analysis, three new compounds, epicatechin-(2 beta-->O-->7, 4 beta --> 6)-catechin, epicatechin-(2 beta --> O --> 7, 4 beta --> 6)-ent-catechin and epicatechin-(2 beta --> O --> 7, 4 beta --> 6)-ent-epicatechin were unambiguously identified, together with the three known compounds, psoanthocyanidin A-1, proanthocyanidin A-2 and epicatechin-(2 beta-->O-->7, 4 beta-->8)-ent-epicatechin. (13)C NMR chemical shift rules to distinguish between [2-->O-->7, 4-->8] and [2-->O -->7,4-->6] double-linked heptamethyl ethers of A-type proanthocyanidins are proposed. Bioassay experiments showed that these six compounds possess substantial activity against hyaluronidase. (C) 1999 Elsevier Science Ltd. All rights reserved.

    Conversion of procyanidin B-type (catechin dimer) to A-type: evidence for abstraction of C-2 hydrogen in catechin during radical oxidation
    摘要:
    Procyanidin B-1 and B-2 were converted into A-1 and A-2 by radical oxidation using 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals under neutral conditions; respectively. Transformation of procyanidin B-type into A-type certainly shows abstraction of the hydrogen atom at the C-2 position during radical oxidation. (C) 2000 Elsevier Science Ltd. All rights reserved.

    formation, and (c) separation of the diasteromers via silica gel column chromatography. The structures of A1 and A2 proanthocyanidins were unequivocally established by analytical comparison to the natural products. Following this methodology, an additional six diastereomers of proanthocyanidins A1 and A2 have been synthesized. A plausible mechanism for the formation of the A-type linkage in proanthocyanidins

    method of doubly linked flavan dimers is reported via the acid-promoted annulation reaction using nascent catechins, (+)-catechin or (-)-epicatechin, as a dianionic partner and an ethylenedioxy-bridged flavan as a dicationic partner. Procyanidins A1 and A2 were synthesized. On the high regioselectivity of the annulation reactions, model experiments and computational studies were carried out.
