中文摘要:

用NBT光化还原法、Fenton反应法和钼酸铵显色分光光度法测定了甜荞(F.esculentum Moench)不同器官(根、茎、叶和花)水提液体外抗羟基自由基(·OH)、超氧阴离子自由基(·O2-)和过氧化氢(H2O2)的能力。结果表明:甜荞不同器官水提液体外均能抗·OH、·O2-和H2O2。抗·OH的能力排序为:茎、花>叶、根;抗·O2-的能力排序为:花>叶、茎>根;抗H2O2的能力排序为:叶、花>根、茎。

英文摘要:

The capacity of resisting ·OH,·O2-and H2O2of aqueous extractions from four organs(root,aerial stem,leaf and flower) of F. esculentum in vitro were estimated by means of nitro blue terra-zolium photochemica reduction,Fenton reaction and spectrophotometric assay. The results showed that the aqueous extractions had the capacity of resisting ·OH,·O2-and H2O2. The capacity of resisting ·OH was sorted as:aerial stem,flower >leaf,root. The capacity of resisting ·O2-was sorted as:flower >leaf,aerial stem >root. The capacity of resisting H2O2was sorted as:leaf,flower >root,aerial stem.
