摘　　要：[目的]从微量元素角度对广西和云南人工种植香菇的营养价值作评价,为了解不同地区人工香菇的药效和营养价值提供科学依据。[方法]采用火焰原子吸收光谱法测定广西和云南人工种植香菇中Zn、Co、N i、Cu、Fe、Cr、Li、Ca和Mg的含量。[结果]2种人工香菇中Mg、Ca、Li、Zn、Fe和Cu含量较高,尤其Mg含量很高,Co、N i和Cr含量较低,广西和云南香菇的Zn/Cu值分别为6.3和3.3。[结论]广西和云南人工香菇中含有丰富的人体所需的微量元素,Zn/Cu值与抗癌中药中微量元素的含量有Zn高Cu低的关系相同,表明这2种香菇具有较高的营养价值,食用香菇可摄入人体所必需的微量元素。[Objective] The purpose was to evaluate the nutritive value of cultivated mushroom in Yunnan and Guangxi Province from the perspective of trace elements and provide scientific basis for studying the drugaction and nutritive value of cultivated mushroom in different districts.[Method] The method of name atomic absorption spectrometry was adopted to determine the content of Zn, Co, Ni, Cu, Fe, Cr, Li, Ca and Mg in the cultivated mushroom in Yunnan and Guangxi Province. [Result] The content of Zn,Co,Ni,Cu,Fe,Cr,Li,Ca and Mg was high in the two kinds of the cultivated mushroom. Mg was higher while the content of Co, Ni and Cr were a bit lower. The Zn/Cu value of cultivated mushroom in Guangxi and Yunnan Province was 6.3 and 3.3 respectively. [ Conclusion ] Cultivated mushroom in Guangxi and Yunnan Province contains abundant of microelements. Zn/Cu value is the same with Anticancer medicine. This proved that this two kinds of mushroom is high of nutritional value and eat mushrooms can absorb trace elements which is necessary for the human body.
