摘要:

摘 要:本文研究了一种从西兰花籽中提取分离萝卜硫苷(4-甲基亚磺酰丁基硫代葡萄糖苷)的方法。用甲醇溶液从西兰花籽中提取硫苷,经弱阴离子交换树脂纯化得到萝卜硫苷粗品,通过半液相制备色谱进一步分离纯化,制得萝卜硫苷纯品。并利用液-质联用、核磁共振、红外、紫外等方法对其进行结构确定,结果符合萝卜硫苷的分子结构。此方法适用于萝卜硫苷的简单有效提取。

Abstract:

A method to isolate and purify gulcoraphanin (4-methylsufinylbutyl glucosionlate) from broccoli seeds was
reported. Gulcoraphanin was extracted from broccoli seeds with a mixture of methanol and water, and purified by DEAESephadex
A25 anion exchange column chromatography. Pure glucoraphanin was obtained by preparative HPLC, and
identified by HPLC-MS, NMR, IR and UV spectroscopy. The results were consistent with the molecular structure of
glucoraphanin. The described method is rapid, robust and suitable for preparing pure glucoraphanin.

Key words: glucoraphanin, broccoli seeds, extraction, isolation, identification
