This is because of the high concentration in Brassicas of substances known as glucosinolates which are metabolized to cancer preentie substances known as isothiocyanates.

这是因为其中含有高浓度的硫代葡萄糖酸盐，它可以代谢成癌症的预防性物质：异硫氰酸盐。

However before this research it was not known how the glucosinolates and isothiocyanates were influenced by storage and cooking of Brassica vegetables.

而在本研究之前，并不清楚硫代葡萄糖酸盐和异硫氰酸盐会因为甘蓝菜的储存和烹饪而受影响。

Isothiocyanates are their degradation products,which have shown a series of biological and chemical characteristics.

硫代葡萄糖甙是存在于十字花科植物中的次生代谢产物，可作为杀虫剂、抗微生物制剂和天然熏蒸消毒剂，其降解产物异硫氰酸酯除具有强烈的辛辣气味可作为调味品外，还具有抑菌、抗病毒和抗癌活性。

Howeer before this research it was not known how the glucosinolates and isothiocyanates were influenced by storage and cooking of Brassica egetables.

而在本研究之前，并不清楚硫代葡萄糖酸盐和异硫氰酸盐会因为甘蓝菜的储存和烹饪而受影响。

The related investigation has indicated that the hydrolytes of glucosinolates existed in horseradish and the other CFV, isothiocyanates show high biological activities.

研究表明CFV中硫甙的水解产物异硫氰酸酯具有高度的生物活性，是CFV是最主要的抗癌活性成分。

In this paper, the structures and the synthesis methods of glycosyl isothiocyanates are summarized, including the application as intermediates in the preparation of glycosylthioureas, glycosylheterocycles, glycosylguanidins and glycosylconjugates and so on.

本文对糖基异硫氰酸酯的结构、制备方法，以及作为中间体在糖基硫脲、糖基杂环、胍基糖苷、糖基缀合物等重要化合物的合成中的应用作了较详尽阐述。

Benzyl isothiocyanate and phenethyl isothiocyanate, are derived isothiocyanates from cruciferous vegetable, including watercress, broccoli and cabbage.

苯甲基异硫氰酸酯和苯乙基异硫氰酸酯是来自於十字花科蔬菜的衍生物，常见的十字花科蔬菜包含了花椰菜、甘蓝菜、芥菜…等。

Furthermore, single-point energy calculations were refined at the QCISD level of theory with the same basis set (6-311++G**). As a result, the singlet reaction of silylene with isothiocyanic acid contain S-atom abstraction channel, N—H inserted channel, and NH abstraction channel, respectively.

又用QCISD/6-311＋＋G**//B3LYP/6-311＋＋G**方法计算了各个驻点的单点能，计算结果表明单重态的硅烯与异硫氰酸的反应有抽提硫、插入、抽提亚氨基的路径。
