  Identification and Quantification of Phenolic Compounds from the Forage Legume Sainfoin (Onobrychis viciifolia)

  摘要：

  Phenolic compounds of sainfoin (Onobrychis viciifolia) variety Cotswold Common are assumed to contribute to its nutritive value and bioactive properties. A purified acetone/water extract was separated by Sephadex LH-20 gel chromatography. Sixty-three phenolic and other aromatic compounds were identified by means of chemical, chromatographic, and spectroscopic methods. Reverse phase HPLC with diode array and chemical reaction detection was used to investigate the phenolic composition of different plant organs. All plant parts showed specific phenolic profiles. Moreover, there were considerable variations in the phenolic content among individual plants of the same variety. The three most abundant phenolic compounds were found to be arbutin [predominant in petiols, 17.7 mg/g of dry weight (DW)], rutin (predominant in leaves, 19.9 mg/g of DW), and catechin (predominant flavanol in petiols, 3.5 mg/g of DW). The present study reveals that the phenolic profile of sainfoin is even more complex than hitherto assumed.

  以对甲氧基苄基奎宁酸酯为关键中间体，通过直接酯化反应高效合成5- O-酰基奎宁酸

  摘要：

  从市售（-）-奎宁酸完成了5- O-酰基奎宁酸的有效和通用合成。我们设计了对甲氧基苄基奎宁酸酯作为关键中间体，并解决了两个问题，即空间位阻的5-OH基团的酯化，以实现简洁的发散合成和最终脱保护步骤的收率低。对于第一个问题，我们通过添加i -Pr 2 NEt改进了田边的方法，即使用游离羧酸的TsCl / NMI介导的酯化反应。对于第二个问题，我们为最终的脱保护步骤建立了TFA或BCl 3 / C 6 HMe 5催化的脱保护反应。5 Ø-酰基奎尼酸通过七个步骤合成，总收率为45-60％。

• Essential structure of co-pigment for blue sepal-color development of hydrangea

  Blue sepal-color of Hydrangea macrophylla might be due to a supramolecular metal-complex pigment consisting of delphinidin 3-glucoside (1), co-pigments (5-O-caffeoylquinic acid (2), and/or 5-O-p-coumaroylquinic acid (3)) and Al3+ in an aqueous solution around pH 4.0. To clarify the mechanism of blue sepal-color development of hydrangea, we tried to reproduce the blue color in vitro by mixing 1 with designed synthetic co-pigments in the presence of Al3+ at pH 4.0. We at first succeeded in clarifying the essential functional structure in the co-pigment that could form the stable blue solution. Here, we present the structure of the blue pigment caused by an Al-complex coordinating of I at ortho-dihydroxyl groups of the B-ring, 1-hydroxy, 1-carboxylic acid, and the carbonyl residue in the ester at 5-position of 2 and/or 3. The hydrophobic interaction between the aromatic acyl residue at 5-position and the nucleus of 1 may also contribute to stabilize the complex. (c) 2005 Elsevier Ltd. All rights reserved.
