    摘要:
    在这项研究中,我们研究了β-和γ-环糊精(γ-CyD)与迷迭香酸(RA)之间的稳定包合配合物(IC)形成,迷迭香酸(RA)是一种具有抗氧化和抗炎作用的物质。使用实验(1 H NMR,FTIR,ICD和XRD,SEM)和计算技术(例如分子动力学模拟和分子对接)制备和表征β-和γ-CyD:RA IC 。热力学参数分析表明,在25°C时,这些IC的摩尔比为1:1(AL型),并且β-和γ-CyD:RA IC的表观稳定常数(K C)形成。 79.07±13.84和63.62±9.31 L mol -1分别。此外,这些结果表明,包封RA到β-和γ-何秀兰的空腔:RA是放热(ΔH 0 通过疏水力和氢键地层驱动<0)。此外,实验和理论方法证实了β-CyD:RA IC比γ-CyD:RA IC更稳定。计算结果还证实了两个稳定IC的形成。这些结果表明,β-和γ-CyDs是有希望的赋形剂,可用于配制包括RA在内的

  • The inclusion complex of rosmarinic acid into beta-cyclodextrin: A thermodynamic and structural analysis by NMR and capillary electrophoresis
    作者:Amra Aksamija、Ange Polidori、Raphaël Plasson、Olivier Dangles、Valérie Tomao

    This work focuses on the characterization of the rosmarinic acid (RA)-beta-cyclodextrin (CD) complex in aqueous solution by H-1 NMR (1D- and 2D-ROESY), completed with studies by capillary electrophoresis (CE). From the H-1 NMR data, the stoichiometry of the complex was determined by a Job's plot and the binding constant was estimated from a linear regression (Scott's method). At pH 2.9, the results showed that RA binds CD with a 1:1 stoichiometry and a binding constant K-b of 445 (+/- 53) M-1 or 465 (+/- 81) M-1 depending on the CD protons (H-5 or H-3) selected for the evaluation. The K-b value was also calculated from the CD-induced chemical shifts of each RA proton in order to collect information on the structure of the complex.The pH dependence of K-b revealed that the RA carboxylic form displays the highest affinity for CD. An investigation by capillary electrophoresis fully confirmed these results. 2D ROESY analysis provided detailed structural information on the complex and showed a strong correlation between H-3 and H-5 of CD and most RA protons. In conclusion, RA, an efficient phenolic antioxidant from rosemary with a marketing authorization, spontaneously forms a relatively stable inclusion complex with CD in water. (C) 2016 Elsevier Ltd.
