选取江西、黑龙江、吉林和安徽4产地同一种属大豆经硝酸湿法消解后,采用电感耦合等离子体原子发射光谱法同时测定了其中K,P,Mg,Ca,Fe,Al,Zn,Mn和Na元素的含量,并采用Ducan多重比较方法对结果进行统计分析.结果表明:大豆中含有丰富的矿物元素,其中K,P,Mg,Ca,Fe元素含量较高,且排序不因产地的变化而改变.Mn,Zn,Al,Na元素的排序则受产地影响较大.K,P,Mg的含量受产地的影响不大,表现出某一品种大豆自身生长对主要矿物质的需求是相对稳定的.不同产地大豆中Al,Ca,Fe,Na,Mn,Zn元素的含最差异显著(P＜0.05),说明这几种微量元素的含量受土壤及环境的影响较大,其中安徽大豆中的铁元素(70.93 mg·kg~(-1))和江西大豆中的锰元素(32.69 mg·kg~(-1))显著高于其他3个样品.

Soybeans from Jiangxi,Heilongjiang,Jilin and Anhui were digested by nitric acid.The contents of mineral elements K,P,Mg,Ca,Fe,Al,Zn,Mn and Na in four samples were analyzed by inductively coupled plasma atomic emission spectrometry(ICP-AES).The differences between samples were determined by Duncan's multiple-range test,and evaluations were based on a significance level of P＜0.05.The results show that soybeans are rich in mineral elements that human body needs.The contents of K,P,Mg,Ca and Fe are higher than the others,and the order from high to low does not change with the producing area.The order of Mn,Zn,Al,Na varied with the producing area.Producting area does not affect the contents of elements K,P and Mg significantly(P＞0.05).It can be concluded that the demands for major mineral elements K,P and Mg are stable in the growth of soybeans with the same variety.However,producing area has a great influence on the contents of elements Al,Ca,Fe,Na,Mn and Zn in soybean(P＜0.05＝.The content of Fe in Anhui soybean(70.93 mg·kg~(-1))and the content of Mn in Jiangxi soybean(32.69 mg·kg~(-1))are significantly higher than the other three samples.The results suggested that the contents of Al,Ca,Fe,Na,Mn and Zn were easily affected by growth conditions,such as water,soil and so on.
