摘　　要：目的对大连地区野生槐花中无机元素进行研究,为探索槐花的药食两用价值,合理开发利用大连野生槐花资源提供参考。方法运用原子吸收分光光度计,分别采用火焰法和氢化物发生法,对大连地区野生槐花中的Mn、Ca Cu、Fe、Na、K、Zn、Mg等8种无机元素以及As、Hg两种有害重金元素进行测定。结果大连野生槐花中8种无机元素的含量由高到低的依次为K 1720.1 ug/g、Ca 882.8μg/g、Mg 777.8μg/g、Na 247.7μg/g、Fe 159.8μg/g、Mn 18μg/g Cu 4.4μg/g、Zn 0.6μg/g;两种重金属Hg、As未检出。结论大连地区野生槐花中对人体有益的无机元素含量丰富;有害重金属未检出;适于药食两用。Objective Determining inorganic elements in wild sophora flowers from Dalian,to explore the medicinal and edible value of sophora flower,and to provide reference for the rational development and utilization of wild sophora flowers resources in Dalian.Methods Eight kinds of inorganic elements of Mn,Ca,Cu,Fe,Na,K,Zn,Mg,and two heavy metal elements of Hg,As in wild sophora flower samples from Dalian were determined through flame method or hydride generation method,with atomic absorption spectrophotometer.Results The contents of eight inorganic elements in sophora japonica flower from high to low were K 1720.1μgg Ca 882.8ug/g、Mg 777.8μg/g Na 247.7μg/g Fe 159.8μg/g Mn 18μg/g.Cu 4.4μg/g.Zn 0.6μglg,respectively.Two heavy metals,Hg and As,were not detected.Conclusion The wild sophora flowers from Dalian are rich in beneficial inorganic elements,and the toxic heavy metals are too low to be detected.Therefore,the wild sophora flowers in Dalian are suitable for both food and medicine.
