聚酰胺是己内酰胺的简称,商业名称叫锦纶、尼龙。聚酰胺分子中含有酰胺基,能与酚类(包括黄酮类),酸类和醌类等形成氢键,因而对这些物质具有吸附作用。黄酮类化合物因酚羟基的数目及位置不同,聚酰胺对它们的吸附力各异。由于聚酰胺对黄酮类化合物吸附力强,分离效果好,故被认为是各类型黄酮体较好的薄层层析吸附剂。 Polyamide is an abbreviation for caprolactam. Its trade name is nylon and nylon. Polyamide molecules contain amide groups that can form hydrogen bonds with phenols (including flavonoids), acids and quinones, and thus have an adsorption effect on these substances. Flavonoids differ in the number of phenolic hydroxyl groups and their positions, and the adsorption of polyamides on them varies. Because polyamide has strong adsorption ability to flavonoids and good separation effect, it is considered as a good thin layer chromatography adsorbent for various types of flavonoids.
