摘  要:
硫代葡萄糖苷的降解产物异硫代氰酸酯具有抗癌活性。采用甲醇沸腾提取法,从萝卜籽中得到硫代葡萄糖苷粗提物。以正丁醇-乙腈-10%硫酸铵溶液(体积比为0.5∶1∶2.2)为溶剂系统,用低速逆流色谱分离硫代葡萄糖苷粗提物得到4-甲基亚磺酰基-3-丁烯基硫代葡萄糖苷(萝卜硫苷)组分,简单的脱盐脱色即可得到萝卜硫苷单体,纯度达95%以上。

摘  要:
Cleavage of glucosinolates with myrosinase yields thioglycosidic compounds have cancer chemoprevention activity. Glucosinolates in the extract from radish seeds were separated by slow-rotary countercurrent chromatography (SRCCC) with the solvent system n-butanol-acetonitrile-10% ammonium sulfate solution 0.5∶1∶2.2 (v/v) to yield one glucosinolate compound. This compound,4-methylsulphinyl-3-butenyl glucosinolate was desalted and decolorized by MCI column chromatography. The purity of the product was higher than 95%.
