Abstract

Patterns of the static sorption of anthocyanins on bentonite clay are determined. It is found that the approach used for static sorption is an alternative to dynamic solid phase purification on DIAPAK C18 concentrating cartridges. A way of determining the relative sorption capacity of anthocyanins characterized by different structures on bentonite clay using the Langmuir equation is proposed. It is shown that the sorption capacity falls as the structure of the glycoside radicals becomes more complicated (from pentoside to hexoside and then to di- and trisaccharides). The acylation of glycoside radicals by malonic acid has a weak effect on sorptive activity, while acylation by substituted cinnamic acids improves sorption.

花青素在膨润土上的吸附

摘要

确定花青素在膨润土上的静态吸附方式。发现在DIAPAK C18浓缩柱上，用于静态吸附的方法是动态固相纯化的替代方法。提出了使用朗缪尔方程确定膨润土上不同结构的花色苷相对吸附能力的方法。结果表明，随着糖苷自由基结构的复杂化（从戊糖苷到己糖苷再到二糖和三糖），吸附能力下降。丙二酸对糖苷自由基的酰化对吸附活性的影响较弱，而肉桂酸取代基的酰化则提高了吸附作用。
