中文摘要：

用蒽酮比色法测定大野荞（Fagopyrum Megaspartanium）不同器官中可溶性糖的含量,并采用NBT光化还原法、Fenton反应法和钼酸铵显色分光光度法研究了大野荞不同器官（茎、叶、花和种子）可溶性糖体外抗羟基自由基（·OH）、超氧阴离子自由基（·O2^-）和过氧化氢（H2O2）的能力。结果表明：大野荞不同器官可溶性糖体外均能抗·OH、·O2^-和H2O2。抗·OH的能力为：花、种子〉茎、叶;抗·O2^-的能力为：花〉叶、种子、茎;抗H2O2的能力为：花、叶〉茎〉种子。

英文摘要：

Total soluble sugar in different organs of Fagopyrum megaspartanium was extracted and determined by anthrone colorimetric method. And the capacity of scavenging·OH,·O2^- and H2O2 of total soluble sugar extracts from four organs（ aerial stem, leaf, flower and seed） of Fagopyrum megaspartanium was also studied by means of nitro blue terra-zolium photochemica reduction, Fenton reaction and spectrophotometric assay. The results showed that total soluble sugar extracts had the capacity of resisting·OH,·O2^- and H2O2. The capacity of resisting ·OH was sorted as： flower, seedaerial stem, leaf. The capacity of resisting·O2^- was sorted as： flowerleaf, seed, aerial stem. The capacity of resisting H2O2 was sorted as： flower, leafaerial stemseed.
