【摘要】 用等离子体质谱、石墨炉原子吸收光谱,荧光分光光度等方法首次测定了人工代料栽培的花脸香蘑子实体中18种元素,测定结果:每克干品中富集金属元素K4112μg,Na132μg,Ca2690μg,Mg1244μg,Fe1215μg,Zn84 4μg,Cu96 8μg,Sr2 39μg,Se0 93μg,Co0 56μg,Ni2 12μg,Ge0 24μg,S0 28μg;富集有害金属元素Pb0 88μg,Cd0 58μg,Hg0 40μg,As1 00μg,Cr1 34μg。研究结果表明,花脸香蘑中富含有人体抗自由基、抗衰老、抗癌微量元素硒、锗、锌,而且富集的有害金属元素较欧洲报道的25种野生蘑菇低约20-100倍。该研究表明,用我们研究的人工代料配方栽培的花脸香蘑品质是优质的,该分析结果对花脸香蘑的食用、药用研究开发具有科学价值。更多还原

【Abstract】 The 18 elements of the product from domestically cultured Lepista sordida were analysed for the first time with Plasma Mass Spectrometer,Graphite Stove Atom Absorption Spectrometer,and Fluorescence Spectrophotometer.The analytical result showed:in 100g of dry matter,there are metal elements K 4112μg,Na 132μg,Ca 2690μg,Mg 1244μg,Fe 1215μg,Zn 844μg,Cu 968μg,Sr 239μg,Se 093μg,Co 056μg,Ni 212μg,Ge 024μg,and S 028μg.The contents for enrichment of harmful elements are as follows:Pb 088μg,Cd 058μg,Hg 040μg,As 100μg,and Cr 134μg.These results are of not only important scientific value,but also practical value for medicinal research and exploitation of this edible fungus.更多还原
