摘要:

采用ICP-MS法同时测定了青海海西州不同地区藜麦中20种矿物质元素,并对其含量进行比较和分析评价,为高原藜麦再加工产品的开发和利用提供依据。采用SPSS 19.0分别对青海海西州3个地区7个不同地点的藜麦之间和青海海西州地区与国内外其他产地的不同颜色藜麦之间各矿物质元素进行多重比较、主成分分析和综合评价。结果表明青海海西州不同地区藜麦之间的Na、B、Al、V、Ni、Se、Ba元素存在显著性差异(P<0.05),青海海西州与国内外其他产地的不同颜色藜麦之间的Na、B、Al、V、Se、Sr、Mo、Ba元素存在显著性差异(P<0.05)。主成分分析结果显示:青海海西州3个地区7个不同地点的藜麦主要分为2类,其矿物质元素质量与当地海拔高度有相关性;青海海西州与国内外其他产地的不同颜色藜麦主要分为5类,其矿物质元素质量除了与当地海拔高度有关外,可能还与引种的藜麦品系、培育和遗传改良、生长环境、生态适应性有关。综合评价分别来自青海海西州的格尔木市大格勒乡和格尔木市乌图美仁乡的藜麦中矿物质元素质量相对更佳,与国内外其他产地的不同颜色藜麦相比,来自青海海西州的白色和红白双色藜麦、秘鲁普诺的红白黑三色藜麦中矿物质元素质量相对更佳。青海海西州地区藜麦矿物质元素丰富,本研究可为其质量控制提供依据。

Abstract:

In this study,a method was developed for simultaneous determination of twenty kinds of mineral elements in Chenopodium quinoa Willd.(CQW) from Haixi Prefecture different regions of Qinghai by inductively coupled plasma-mass spectrometry (ICP-MS).The contents of these mineral elements were selected to compare,analyze and evaluate,providing a basis for the development and utilization of the CQW reprocessed products in Qinghai Plateau.SPSS 19.0 was used to conduct multiple comparative analysis,principal component analysis and comprehensive evaluation of mineral elements between the CQW in seven different locations from three Haixi Prefecture regions,and the CQW from Qinghai Haixi Prefecture regions and other domestic and foreign producing areas were also made.The results showed that there were significant differences (P<0.05) in Na,B,Al,V,Ni,Se and Ba of the CQW from different Haixi Prefecture regions of Qinghai,and there were significant differences P<0.05) in Na,B,Al,V,Se,Sr,Mo and Ba of the CQW between Qinghai Haixi Prefecture regions and other domestic and foreign producing areas.The results of principal component analysis showed that the CQW in seven different locations from three Haixi Prefecture regions of Qinghai was mainly divided into two categories,and the quality of mineral elements were correlated with local altitude;the CQW of different colors in Haixi Prefecture regions of Qinghai and other domestic and foreign producing areas was mainly divided into five categories,and the quality of mineral elements were not only related to local altitude,but may also be related to introduced quinoa strains,breeding and genetic improvement,growing environment and ecological adaptability.After comprehensive evaluation,the quality of mineral elements in the CQW of Dagele Township,Geermu City and Wutumeiren Township,Geermu City from Haixi Prefecture regions of Qinghai were relatively better,respectively.Compared with the CQW of different colors from other domestic and foreign producing areas,there were relatively better quality of mineral elements in the CQW of pure white,a double colors of red and white from Haixi Prefecture regions of Qinghai,and the CQW with a three colors of red,white and black from Peru puno.This study can provide a basis for quality control of the CQW in Haixi Prefecture regions of Qinghai with rich in mineral elements.
