摘要
以6个萝卜品种为试材,对其肉质根中的硫代葡萄糖苷(硫苷)组分及含量进行了测定分析。结果表明:不同萝卜品种中硫苷总量相差较大,秋红萝卜类型的京红3号含量最高,为480.9μmol·kg-1(FW),其次是京研水果型萝卜,为318.8μmol·kg-1(FW);含量最低的是满堂红,为213.9μmol·kg-1(FW),仅为京红3号的44%。对萝卜中的硫苷组分进行分析,检测出了5种类型的硫苷,分别为4-甲基亚磺酰基-3-丁烯基硫代葡萄糖苷、4-羟基吲哚-3-甲基硫代葡萄糖苷、4-甲硫基-3-丁烯基硫代葡萄糖苷、吲哚-3-甲基硫代葡萄糖苷及4-甲氧基吲哚-3-甲基硫代葡萄糖苷。6个萝卜品种中的硫苷均以4-甲硫基-3-丁烯基硫代葡萄糖苷为主,占总含量的70.5%～87.5%。
Glucosinolates composition and contents were evaluated taking 6 radish（Raphanus sativus L.）cultivars as experiment materials.The result indicates that there are great differences among total glucosinolates contents of different radish cultivars.＇Jinghong No.3＇,an autumn-red radish,has the highest total glucosinolate content 480.9μmol·kg-1（FW）,followed by＇Jingyanshuiguoxingluobo＇ 318.8μmol·kg-1（FW）.The lowest concent is found in＇Mantanghong＇213.9μmol·kg-1（FW）,taking 44%of＇Jinghong No.3＇content.After analyzing glucosinolates composition,we find 5 types of radish glucosinolates,including 4-methylsulfinyl-3-butenyl-glucosinolates,4-hydroxyindol-3methyl-glucosinolates,4-methylthio-3-butenyl-glucosinolates,indol-3-methyl-glucosinolates and 4-methoxyindol-3-methyl-glucosinolates.The predominant glucosinolate in 6 radish varieties is 4-methylsulfinyl-3-butenyl-glucosinolate representing,taking about 70.5%-87.5%of the total amount.
