。 能够减轻眼疲劳、 提高黑暗中视力以及视觉瞬间改变适应能力, 对人视觉具 有保护作用, 对近视、 单纯绿内障、 视网膜炎色盲具有改善作用。
花色苷是花青素的糖苷衍生物, 自然条件下游离的花青素(anthocyanidin) 极少见, 而常与一个或多个葡萄糖、 鼠李糖、 半乳糖、 木糖、 阿拉伯糖等通过 糖苷键形成花色苷(anthocyanin)。 花色苷基本结构如下:
Figure imgf000003_0001
Rl和 R2是 H、 OH或者 OCH3, R3是糖基或 H, R4是糖基或 OH。
花色苷化学结构中含有多个羟基, 具有较强的极性和一定的水溶性, 脂溶性较 差, 化学稳定性差, 随着存在环境的变化而发生转变。 花色苷类物质通常生物 利用度较低, 不利于某些药用制剂的应用。 为了提高其稳定性和生物利用度, 我们釆用制备成磷脂复合物的方法, 提高花色苷的化学稳定性和生物利用度。
[7] 磷脂普遍存在于动植物细胞的原生质和生物膜中, 对生物膜的生理活性和机体 的正常代谢有重要的调节功能。 磷脂是含磷酸根的脂类物质, 属天然元素有机 化合物, 它既有表面活性, 又具有生物活性, 是特种表面活性剂。 磷脂分子具 有一个亲水性的头部和两条疏水长链, 其结构式如下式:
