摘要:
用大麦苗分析单一硒(Se)、谷胱甘肽(GSH)和Se+GSH处理15 d对大麦苗富集Se与GSH及其抗氧化特性的影响。结果显示,Se+GSH复合处理比单一Se或GSH处理增加了大麦苗对Se和GSH的积累量。抗氧化酶系统在Se+GSH复合处理与Se或GSH单一处理之间存在差异。Se+GSH复合处理的大麦苗过氧化氢酶(CAT)和谷胱甘肽S-转移酶(GST)的活性高于Se或GSH单一处理,相反,过氧化物酶(POD)活性则低于Se或GSH处理。Se+GSH处理超氧化物歧化酶(SOD)的活性比GSH处理低,而抗坏血酸过氧化物酶(APX)活性则比GSH处理高。Se+GSH复合处理条件下谷胱甘肽还原酶(GR)的活性大于Se处理而小于GSH处理。Se+GSH处理的大麦苗丙二醛(MDA)含量无明显变化,而总抗氧化能力(T-AOC)显著提高。说明Se+GSH复合作用比单一GSH或Se更有利于促进GSH和Se的吸收与积累,同时增强抗氧化效果。
