  Chemical Synthesis of Hydroxycinnamic Acid Glucosides and Evaluation of Their Ability To Stabilize Natural Colors via Anthocyanin Copigmentation

  摘要：

  This work describes the chemical synthesis of O-aryi-beta-D-glucosides and 1 -O-beta-D-glucosyl esters of hydroxycinnamic acids. In particular, OLaryl-beta-D-glucosides were efficiently prepared via a simple diastereoselective glycosylation procedure using phase transfer conditions. Despite the lability of its ester linkage, 1-O-beta-D-caffeoylglucose could also be obtained using a Lewis acid catalyzed glycosylation step and a set of protective groups that can be removed under neutral conditions. Hydroxycinnamic acid O-aryl-beta-D-glucosides were then quantitatively investigated for their affinity for the naturally occurring anthocyanin malvin (pigment). Formation of the pi-stacking molecular complexes (copigmentation) was characterized in terms of binding constants and enthalpy and entropy changes. The glucosyl moiety did not significantly alter these thermodynamic parameters, in line with a binding process solely involving the polyphenolic nuclei.

  The dicaffeoyl anthocyanin, phacelianin, was isolated from blue petals of Phacelia campanularia. Its structure was determined to be 3-O-(6-O-(4'-O-(6-O-(4'-O-beta-d-glucopyranosyl-(E)-caffeoyl)-beta-d-glucopyranosyl)-(E)-caffeoyl)-beta-d-glucopyranosyl)-5-O-(6-O-malonyl-beta-d-glucopyranosyl)delphinidin. The CD of the blue petals of the phacelia showed a strong negative Cotton effect and that of the

  双咖啡酰花青素，phacelianin，是从Phacelia campanularia 的蓝色花瓣中分离出来的。其结构被确定为 3-O-(6-O-(4'-O-(6-O-(4'-O-β-d-吡喃葡萄糖基-(E)-caffeoyl)-β-d-吡喃葡萄糖基)-(E)-咖啡酰)-β-d-吡喃葡萄糖基)-5-O-(6-O-丙二酰-β-d-吡喃葡萄糖基)飞燕草素。phacelia蓝色花瓣的CD显示出强烈的负Cotton效应，有色原生质体悬浮液的CD相同，表明phacelianin的生色团可能在蓝色液泡中以逆时针堆积的方式进行分子间堆积. 在弱酸性水溶液中，phacelianin 在 CD 中显示出与花瓣相同的蓝色和负棉花效应。然而，在没有金属离子的情况下逐渐形成蓝黑色沉淀。可能需要极少量的 Al(3+) 或 Fe(3+) 来稳定蓝色溶液。Phacelianin 可能同时采取分子间和分子内堆积的形式，通
