紫外分光光度法对大酱中异黄酮总含量的分析比较

Comparison of contents of isoflavones from pastes of Harbin market by ultraviolet spectrophtometry

以染料木苷为标准品,利用三波长紫外分光光度法对哈尔滨市售的若干大酱产品进行了大豆异黄酮含量的测定。测定结果表明,“香其酱”和“正阳河”的大豆异黄酮平均测定含量较高,分别达到了0.064%和0.068%,而“松岛”的含量较低,仅有0.011%。

Using genistin as standard, isoflavones contents of some pastes in Harbin market were determined by three wavelength ultraviolet spectrophotometry. ＇Xiangqijiang＇ and ＇Zhengyanghe＇ were the two varieties that contained higher contents of isoflavones, and their contents were 0. 064 % and 0. 068 % respectively. ＇ Songdao＇ contained a lower contents of isoflavones of 0. 011%.
