【摘要】 异硫氰酸酯是一类具有抗癌作用的物质,本文用二氯甲烷从7种芸苔属植物(花椰菜,白菜,甘蓝,芥蓝,羽衣甘蓝,大头菜,西兰花)和萝卜等种子的水解液中提取出硫代葡萄糖苷水解产物,经气相-质谱联用分析组分,分析出12种异硫氰酸酯等化合物,主要有异硫氰酸烯丙酯、异硫氰酸3-丁烯酯、异硫氰酸苯乙酯、萝卜硫素、告伊春(goitrin)、 iberin、iberverin、sulforaphene 等,并用气相色谱法测定了含量。其中萝卜硫素主要存在于西兰花种子中,苯乙酯存在于大头菜、花菜种子中,sulforaphene 主要分布在萝卜种子中, 烯丙酯和3-丁烯酯在大多数种子中都存在。更多还原

【Abstract】 Isothiocyanates,which are rich in Cruciferae family,have been shown to have anticarcinogenesis abilities.In order to produce diet supplement that can supply beneficial isothiocyanates,the isothiocyanates pattern and content of 7 Brassica species(cauliflower, Chinese cabbage,cabbage,Chinese kale,kale,root mustard,broccoli)and radish were analyzed in this article.Glucosinolates autolysis products of seed meal were extracted by methylene chloride and then analyzed by GC-MS and GC-FID.More than 12 compounds were identified.The results showed that the main compounds were allyl isothiocyanates,3-BITC,PEITC,sulforaphane, goitrin,iberin,iberverin,sulforaphene,dehydroerucin,etc.Sulforaphane was found mainly in broccoli,PEITC was found mainly in root mustard and cauliflower,sulforaphene was found only in radish.Allyl isothiocyanate and 3-BITC were found in most species of Brassica L.更多还原
