【摘要】 对9种中国十字花科芸薹属白菜类、芥菜类和甘蓝类蔬菜的硫代葡萄糖苷(简称硫苷)组成与含量进行了评价。结果表明,散叶甘蓝硫苷总含量最高,其次是包包青菜、包心芥菜、芥蓝, 小白菜的含量最低。不同的品种硫苷的类型和含量不同。白菜类中,小白菜主要的硫苷为3-丁烯基和1-甲氧基-3-吲哚基甲基硫苷,菜心中为3-丁烯基和2-羟基-3-丁烯基硫苷,薹菜中为1-甲氧基-3-吲哚基甲基和4-戊烯基硫苷。在芥菜类中,发现了两种不同硫苷类型,烯丙基硫苷是包包青菜、包心芥菜主要的硫苷,约占总含量的90％;而在小叶芥中3-丁烯基为主要的硫苷,占总含量的大约70％。甘蓝类中羽衣甘蓝主要含有3-吲哚基甲基硫苷和3-甲基硫氧丙基硫苷。4-甲基硫氧丁基硫苷的含量以芥蓝中最高,此外3-丁烯基硫苷的含量也比较高。在散叶甘蓝中,2-羟基-3- 丁烯基硫苷是主要的组成,约占总含量的43％,烯丙基硫苷和3-吲哚甲基硫苷占总含量的20％左右,芥蓝中萝卜硫素前体4-甲基硫氧丁基硫苷的含量可达124．1μmol／100gFW,是很有抗癌价值的十字花科蔬菜。更多还原

【Abstract】 Glucosinolates (GS) composition and contents were evaluated in Chinese Brassica vegetables including pak choi-(B. campestris), mustard- (B.juncea) and cole groups (B. oleracea). Among of the 9 Brassicas, collard had the highest total glucosinolate content, followed by baobaoqingcai, cabbage mustard and Chinese kale. The lowest concentration was found in pak choi. Glucosinolate profiles and contents varied among of the different groups and within each group. The main glucosinolates in pak choi were 3-butenyl and 1-methoxy-3 -indoylmeth -yl-glucosinolates, in choy sum 3-butenyl- and 2-hydroxy-3-butenyl-glucosinolates and in tai tsai 1-methoxy-3-indoylmethyl- and 4-pentenyl- glucosinolates. Two types of glucosinolate profiles were detected in mustard group. 2-Propenyl-GS was the major glucosinolate representing about 90% of the total amount in cabbage mustard and in baobaoqingcai. Whereas in pot herb mustard. 3-butenyl-GS was the dominant glucosinolate representing about 70% of the total. The predominant glucosinolates in kale were 3-indolylmethyl- and 3-methylsulphinylpropyl- glucosinolates. High amounts of 4-methylsulfinylbutyl-GS were only determined in Chinese kale. Besides, 3-butenyl-GS was also a dominant glucosinolate found in Chinese kale. In collard 2-hydroxy-3-butenyl-GS was the predominant glucosinolate with 43% of the total amount: 2-propenyl- and 3-indolylmethyl- glucosinolates were also present with about 20% of the total, glucoraphanin content in Chinese kale reached 124.1μmol/100g FW which could be regarded as the valuable Brassica vegetable for anti-tumor.更多还原
