摘要
不同摩尔配比的 β 环糊精 /卵磷脂的甲醇 水溶液的紫外吸收光谱和固体包结化合物的元素分析结果表明 ,约 2分子的 β 环糊精和 1分子的卵磷脂依据范德华作用力和疏水作用力等发生包结作用 ,生成了稳定的包结化合物。
A kind of cyclic oligosaccharides,β-cyclodextrin (β-CD) was found to possess inclusion ability with phosphatidylcholine (PC).The inclusion compound of β-CD with PC was studied by elemental analysis of solid inclusion compound and UV spectra of different mole ratios β-CD/PC in H 2O-MeOH solution.The results indicate that two moles of β-CD include one mole PC to form inclusion compound by Van Der Waals force,hydrophobic interaction and hydrogen bounds,etc.The selective binding ability of β-CD with PC has been discussed from the viewpoint of size/shape-fitting and geometry fitting between the host cavity and the gust molecular.The solubility in aqeous solution,the oxidation stability of PC was increased by inclusion with β-CD.
