摘要
采用ICP-AES法测定了绒柄牛肝菌中11种微量元素含量。结果显示,Mg和Fe含量最高(>100mg.kg-1),Mn,Zn,Cu含量较高(>10 mg.kg-1),Cr,Pb,Ni,Cd,As含量较低(>0.1 mg.kg-1),Hg含量最低(<0.1 mg.kg-1)。所测定的元素中,Zn和Cu存在显著正相关(P<0.05),相关系数为0.659。而Hg与As,Ni与Fe,Zn与Mg分别存在显著负相关(P<0.05),相关系数为-0.672,-0.610,-0.617。本研究为绒柄牛肝菌的开发利用与质量评价提供一定的理论依据。
The contents of eleven trace elements in Boletus tomentipes were determined by inductively coupled plasma atomic emission spectroscopy(ICP-AES).The results showed that the fruiting bodies of B.tomentipes were very rich in Mg and Fe(〉100 mg·kg-1) and rich in Mn,Zn and Cu(〉10 mg·kg-1).Cr,Pb,Ni,Cd,and As were relatively minor contents(0.1-10.0 mg·kg-1) of this species,while Hg occurred at the smallest content(〈0.1 mg·kg-1).Among the determined 11 trace elements,Zn—Cu had significantly positive correlation(r=0.659,P〈0.05),whereas,Hg—As,Ni—Fe,and Zn—Mg had significantly negative correlation(r=-0.672,-0.610,-0.617,P〈0.05).This paper presented the trace elements properties of B.tomentipes,and is expected to be useful for exploitation and quality evaluation of this species.
