太空育种射干的X射线荧光及X射线衍射分析和表征

联用X射线荧光光谱(XRF)和粉末X射线衍射(PXRD)方法,对我国独创的第4代太空诱变育种射干中多种元素种类和含量及晶态物质进行了研究。结果表明:太空组射干K元素含量比地面组、对照品分别提高了1.03和0.31倍,Mg元素分别提高了1.44和0.06倍,Ca,Mn和Fe元素含量比地面组分别提高了0.95,0.30和0.29倍,Al元素比地面组、对照组分别降低了38.5%和85.5%,并在射干中鉴别出一水草酸钙(CaC2O4.H2O)晶体,晶体含量是地面组<太空组<对照品。从而可得出结论:太空射干中人体必需的矿质元素比地面组都更接近或优于对照品。文章研究结果和方法对筛选品质优良的太空药材籽种和推广种植太空药材以及建立中药材质量评价标准,有积极的作用和重要意义。

Analysis and Characterization of Belamcanda Chinensis with Space Mutagenesis Breeding by X-ray Fluorescence Analysis and X-ray Diffraction

The contents of various elements in the fourth generation Belamcanda chinensis(L.)DC.with space mutagenesis breeding were analyzed and characterized.X-ray fluorescence spectrum analysis(XRF) and powder X-ray diffraction(PXRD) were applied jointly.It was found that the content of K element in the space flight mutagenesis increases 1.03 and 0.31 times,Mg enhances 1.44 and 0.06 times,but Al reduces 38.5% and 85.5% respectively compared to the contents in the ground group and the comparison group,while those of Ca,Mn and Fe enhance 0.95,0.30 and 0.29 times respectively contrasted to the ground group.Besides,there was discovered the crystal of whewellite in the Belamcanda chinensis(L.)DC.and the content in the ground group is less than that of the outer space and the outer space group,which in turn is less than that of the comparison group.It is concluded that the contents of mineral elements indispensable to body in the space group are closer or superior to the comparison,group as compared to the ground group.In the present paper,a quick and simple appraising method is offered,which may be of great significance to the popularization of the planting outer space Chinese traditional medicine to filtrate more excellent breed and set up norm of quality appraisal.
