硒对芥蓝硫代葡萄糖苷含量与组分的影响

Effect of Selenium on Glucosinolates Content and Component in Chinese Kale

采用高效液相色谱法(HPLC)对不同浓度亚硒酸钠处理的芥蓝植株中硫代葡萄糖苷(glucosinolates,简称硫苷)组分及含量进行测定分析。结果表明,芥蓝地上部和根中分别含有9种和8种硫苷组分,分属于脂肪族硫苷和吲哚族硫苷,未检测到芳香族硫苷。不同浓度亚硒酸钠处理对芥蓝植株不同部位总硫苷、脂肪族硫苷、吲哚族硫苷含量的影响不同,大多在5μmol·L-1浓度水平达到最高值;不同浓度亚硒酸钠处理对地上部各硫苷组分含量的影响程度均大于根部。

This paper measured and analyzed the component and content of glucosinolates in Chinese kale plants treated by sodium selenite of different concentration by HPLC.The results showed that the leaves and roots of overground parts broccoli contained 9 and 8 kinds of glucosides,respectively.They belonged to aliphatic glucosinolates and indole glucosinolates.No aromatic glucosinolates was detected.The effects of treatments by different sodium selenite concentration on the total glucosinolates,aliphatic glucosinolates and indole glucosinolates contents in different parts of Chinese kale plants were different.Most of them reached the highest value under the treatment of 5μmol·L-1 sodium selenite.The incidence of treatments by different sodium selenite concentration on the constituent contents of various glucosinolates in overgound plant parts are bigger than in roots.
