摘要: 本文采用涂渍AgNO3的离心旋转薄层层析法,利用其分离速度快,分离量大,固定相利用率高,分离效果好及Ag+对双键位置及构型作用灵敏等优点,使乙酰化漆酚得到了满意的分离。
对漆酚的五个主要组分,采用1H、13C-NMR技术,确定了它们的结构与谱线归属。同时,质谱数据也证实了它们的结构。

Abstract: The urushiol diacetate derived from urushiol have been successfully separated using centrifugal rotational TLC with preparative silica gel thin layer coated by silver nitrate. The method gave rapid separation of a large amount of different kinds of urushiol diacetatcs. Because the silver ion is very sensitive to the degree of unsaturation and configuration of the unsaturated bonds, urushiol di-acetates were well separated. We are satisfied that the five main components were good enough in purity and quantity for NMR study.
The structure and configuration of key components of urushiol were determined successfully by 1H and 13C-NMR. The assignment of resonances for 1H and 13C were defined. In addition, they were confirmed by MS.

Key words: Urushiol, NMR
