采用电感耦合等离子体原子发射光谱法(ICP-AES)对55个云南省水稻改良品种精米、糙米及其相应的土壤18种矿质元素进行测定与分析,加标回收率在93.1%～110.2%之间,RSD为0.8%～5.1%。18种矿质元素(S,Mo,Ba,Ni,Fe,Cr,Na,Al,Cu,P,Sn,Zn,B,Mn,Mg,Ca,Sr和K)是功能稻米活性成分的重要部分,精米的平均含量依次为P>K>S>Mg>Ca>Zn>Na>Al>Mn>Fe>Cu>B>Mo>Ni>Sn>Cr>Ba>Sr,糙米P>K>Mg>S>Ca>Zn>Mn>Al>Na>Fe>Cu>B>Mo>Sn>Ni>Cr>Ba>Sr,而土壤则为Fe>Al>Ca>K>Mg>P>S>Mn>B>Na>Ba>Zn>Cr>Cu>Ni>Sn>Mo>Sr;精米和糙米除S和P外,16种矿质元素含量均明显低于土壤;精米和糙米间八种微量元素(Mo,Ni,Cr,Sr,Mn,Zn,Cu,Na)间相关性明显比六种宏量元素(P,K,Mg,Ca,S和Al)间关系密切。云南土壤以富铁铝高钙为主而精米和糙米则以磷钾镁硫为主;以精米为主食比糙米更易诱发慢性病。文章结果可能为功能稻米遗传育种、生产以及人类慢性病和矿质营养不良(Fe,Zn和Ca)问题研究的参考。
In this paper, ICP-AES was used to determine and analyze 18 mineral elements in rice, brown rice and their corresponding soils in 55 improved rice varieties in Yunnan Province. The recoveries of spiked samples ranged from 93.1% to 110.2% Between, RSD is 0.8% ~ 5.1%. 18 kinds of mineral elements (S, Mo, Ba, Ni, Fe, Cr, Na, Al, Cu, P, Sn, Zn, B, Mn, Mg, Ca, Sr and K) are important parts of functional rice, The average contents of polished rice were P> K> S> Mg> Ca> Zn> Na> Al> Mn> Fe> Cu> B> Mo> Ni> Sn> Cr> Ba> Sr, brown rice P> K> Mg> S > Ca> Zn> Mn> Al> Na> Fe> Cu> B> Mo> Sn> Ni> Cr> Ba> Sr, while Fe> Al> Ca> K> Mg> P> S> Mn> B The contents of 16 mineral elements in polished rice and brown rice except S and P were significantly lower than those in the soil. Eight trace elements (Mo, Ni, Cr, Sr, Mn, Zn, Cu, Na) were significantly correlated with the six macroelements (P, K, Mg, Ca, S and Al) The soil of Yunnan is mainly iron-rich, high-calcium and rice and brown rice are dominated by phosphorus, potassium, magnesium and sulfur. The main diet of polished rice is more likely to induce chronic diseases than brown rice. The results of this article may be useful reference for the research of functional rice breeding, production and human chronic diseases and mineral malnutrition (Fe, Zn and Ca).
