    桦树皮原花青素的硫解作用:原花青素形成 2,3-cis-3,4-cis-flavan-4-benzylthioethers 的结构依赖性
    摘要:
    摘要 桦树皮原花青素、表儿茶素-(4β→8)-儿茶素 (B1)、表儿茶素-(4β→6)-儿茶素 (B7) 和表儿茶素-(4β→8)-表儿茶素-(4β→8) 的硫解研究- 儿茶素,除了已知的 β-硫醚外,还提供了第一个 2,3-cis-3,4-cis-flavan-4-benzylthioethers 存在的证据。它们的形成取决于“下部”末端黄烷单位的 2,3-立体化学,并且显然取决于类黄酮间连接的相对不稳定性。相比之下,表儿茶素-(4β→8)-表儿茶素(B2)、表儿茶素-(4β→6)-表儿茶素(B5)和表儿茶素-(4β→8)-表儿茶素-(4β→8)-表儿茶素(C1),仅提供 2,3-cis-3,4-trans-flavan-4-benzylthioethers。

    A chemical examination of the bark of Cinnamomum cassia( ?? ?? ?? ?? : Lauraceae) has led to the isolation of three flavan-3-ol glucosides (1-3) and three oligomeric procyanidins (4-6) named cinnamtannins A2-A4, together with (-)-epicatechin(7), procyanidins B-2 (8), B-5 (9) and C-1 (11), and a doubly-linked proanthocyanidin (10). On the basis of chemical and spectroscopic evidence, compounds 1-3 were characterized as (-)-epicatechin 3-O-, 8-C- and 6-C-β-D-glucopyranosides, respectively, while compounds 4-6 were shown to be tetrameric, pentameric and hexameric procyanidins, respectively, consisting exclusively of (-)-epicatechin units linked linearly through C(4β)-C(8) bonds.

    A proanthocyanidin trimer (1), two tetramers (2 and 3) and a pentamer (4) have been isolated from the root bark of Cinnamomum sieboldii MEISNER (Lauraceae). The structures of these compounds were established by acid-catalyzed thiolytic degradation, in conjunction with proton and carbon-13 nuclear magnetic resonance analyses. In addition, the presence of (-)-epicatechin (13), (+)-catechin (14) and known proanthocyanidins B-1 (5), B-2 (6) and B-5 (7), trimers (8 and 9), tetramers (10 and 11) and a pentamer (12) in this plant was demonstrated.

    The chemical structure of the purified proanthocyanidin polymers of Lotus corniculatus was analysed by 13C NMR 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
