目的给大麦草的开发利用提供必要的理论依据。方法以用大麦青苗为实验材料,对分裂旺盛期的大麦苗进行系统的微量元素含量分析,用原子吸收分光度法测定大麦青苗中铁(Fe)、铜(Cu)、镁(Mg)、钙(Ca)、锰(Mn)、锌(Zn)、硒(Se)八种微量元素的含量。结果大麦草中钾、钙、镁的含量最大,其次是铁、硒、锌三元素,含量最少的是铜和锰。结论大麦草中含有丰富的人体必需的微量元素。 Objective To provide the necessary theoretical basis for the development and utilization of barley grass. Methods Using the barley young plant as the experimental material, the content of trace elements in barley seedlings was analyzed systematically. The contents of Fe, Cu, Mg and Ca (subscript 2 +) in barley young plantlets were determined by atomic absorption spectrometry. Ca, Mn, Zn and Se. Results The content of potassium, calcium and magnesium in barley grass was the largest, followed by the three elements of iron, selenium and zinc, and the least content was copper and manganese. Conclusion Barley grass is rich in essential trace elements.
