红枣微量元素含量测定分析

Determination Analysis of Trace Element in Chinese Jujubes

利用微波消解-原子吸收分光光度法,测定分析红枣中微量元素含量,发挥不同品种红枣的药用和食用价值。红枣中6种微量元素含量分别是:铁21.01mg/kg～31.09mg/kg,钙607.40mg/kg～787.80mg/kg,铜1.97mg/kg～3.58mg/kg,锌6.46 mg/kg～14.91mg/kg,锰2.64 mg/kg～3.67 mg/kg,镁358.60 mg/kg～431.40 mg/kg。结果表明:红枣中微量元素的含量丰富,尤其是钙、镁、铁的含量较高。
