  Stable Isotope Labeling Pattern of Resveratrol and Related Natural Stilbenes

  摘要：

  The stable isotope characterization of resveratrol 1 from Polygonum cuspidatum and of related natural stilbenes 11 and 12 obtained by hydrolysis of the corresponding glucosides 2 and 3 from Rheum is reported. The C-6-C-2-C-6 framework of suitably protected derivatives of 1, 2, and 3 has been degraded with ozone to the C-6-C-1 aldehydes 4, 5, 9, and 10, retaining all hydrogen atoms of the precursors. The natural and synthetic derivatives are characterized and distinguished by natural abundance deuterium nuclear magnetic resonance studies. In the case of anisaldehyde 4 the two series show, as expected, the characteristic difference of the aromatic labeling. The formyl deuterium contents of 4 and 5 from resveratrol are remarkably different, seemingly reflecting the different enrichments existing between positions 3 and 2, respectively, of the phenylpropanoid precursor. The positional delta(18)O values of the extractive materials 1-3 were also determined. In this instance a selective deoxygenation procedure was adopted, leading from 1 to the products 6, 7, and 8. The delta(18)O values of the latter compounds reveal, respectively, those at position 4' and positions 3 and 5 of 1. Similarly, the phenolic products 11 and 12 were converted into 13 and 14. From the delta(18)O values of the single components it is possible to design a detailed map of the oxygen fractionations which characterizes the stilbenes 1-3. In particular, the oxygen present at position 4' of the phenylpropanoid moiety of 1-3 shows delta(18)O values of +11.5, +1.8, and +6.7parts per thousand, respectively. Moreover, the phenolic oxygen atom at position 3' of rhapontin 3 shows a value of +11.7parts per thousand. The data are compared with those previously obtained on structurally related compounds. These results show the utility of simple chemical degradations in the stable isotope characterization of structurally complex food components.

  摘要：

  发现从5种大黄中提取的甲醇对DPPH自由基和.O2-具有清除活性。从大黄（Rheum undulatum L.）的根茎中分离出两个新的蒽醌葡糖苷，以及两个蒽醌葡糖苷，萘葡糖苷和10个对苯二酚。在对大黄成分的自由基清除活性的筛选试验中，丁苯二酚和萘葡萄糖苷具有活性，而蒽醌和番石榴苷则没有活性。此外，大多数对苯二酚通过叔丁基氢过氧化物抑制红细胞膜的脂质过氧化。对各种相关化合物的清除作用的详细研究表明以下结构要求；1）酚羟基对显示活性至关重要；2）没食子酰基部分增强活性；3）葡糖苷部分降低活性；4）二氢二苯乙烯衍生物保持对DPPH自由基的清除活性，但它们对.O2-的活性较弱。另外，具有3-羟基和4'-甲氧基的几个对苯二酚抑制黄嘌呤氧化酶。

  The species of microalgae examined displayed a particular sensitivity toward the evaluated compounds at low ng/mL concentrations. It was shown that several of the natural and synthetic compounds exerted their repelling activities via nontoxic and reversible mechanisms. The activities of the most active compounds such as 3,5-dimethoxybibenzyl (5), 3,4-dimethoxybibenzyl (9), and 3-hydroxy-3′,4,5′-trimethoxybibenzyl

  本研究报告了对海洋环境中化感作用的陆地天然产物作为防污剂的首次综合评估。为了研究天然二氢二苯乙烯支架的防污潜力，制备了22种具有不同取代模式的合成二氢二苯乙烯类化合物的文库，并评估了它们的防污能力，其中许多取代型自然存在于陆生植物中。在针对16种污染海洋生物的广泛筛选中评估了这些化合物。研究表明，二氢二苯乙烯骨架对海洋微污垢和大型污垢均具有强大的一般防污效果，并在低浓度下具有抑制活性。在低ng / mL浓度下，所检查的微藻物种对所评估的化合物表现出特殊的敏感性。结果表明，几种天然和合成化合物均通过无毒和可逆的机制发挥其排斥作用。活性最高的化合物，例如3,5-二甲氧基联苄（5），3，4-二甲氧基联苄基（9）和3-羟基-3′，4，5′-三甲氧基联苄基（20）与用作防污助剂的商业防污剂Sea-n相当。陆地化感化天然产物对付海洋污染的研究代表了一种设计“绿色”防污技术的新颖策略，这些化合物为传统的杀生物防污剂提供了潜在的替代品。

  A phytochemical investigation of Tragopogon orientalis L. (Asteraceae, Cichorieae) yielded the natural products 6 ''-O-(7,8-dihydro-caffeoyi)-alpha,beta-dihydrorhaponticin, 3 '-O-methyl-alpha,beta-dihydrorhaponticin, and (S)-3-(4-beta-glucopyranosyloxybenzyl)-7-hydroxy-5-methoxyphtalide as well as known compounds alpha,beta-dihydrorhaponticin, 3-(4-methoxybenzyl)-5,7-dimethoxyphthalide, p-dihydrocoumaric acid methyl ester, and 1-hydroxypinoresinol-1-O-beta-glucopyranoside. The structures were established by HR mass spectrometry, extensive 1D and 2D NMR spectroscopy, and CD spectroscopy. Moreover, the radical scavenging activities of the major compounds were measured using the 2,2-diphenyl-l-picrylhydrazyl (DPPH) assay. The chemosystematic impact of the occurrence of stilbene derivatives in T orientalis is discussed. (c) 2006 Elsevier Ltd. All rights reserved.
