摘　　要：采用X射线荧光光谱法(XRF)对第4代太空组和地面组丹参药用部分的元素种类和含量进行测定和对比分析,为航天育种中药材筛选品质优化的新品种及深入研究积累数据。结果表明,太空丹参元素种类没有变化,但Cu/Zn比值由地面组的0.68提高到1.0,Cr,Mn,Fe的含量分别提高了0.6,0.5,0.3倍,显示太空丹参多种元素指标明显优化。XRF方法简单快捷,具有测定元素种类多、含量范围广、灵敏度高的特点,可以从整体上对中药材的元素进行测定分析和研究。X-ray fluorescence spectrum（XRF）analytic method was used to analyze and compare the contents and varieties of mineral elements in the ground group Salvia miltiorrhiza Bge, and the fourth generation Salvia miltiorrhiza Bge with space flight mutagenesis breeding in order to provide important basic data for selecting high quality breed and further research. The result indicates that the varieties of the main mineral elements in the two samples are the same basically, but Cu/Zn ratio is enhanced to 1.0, the contents of microelements Cr, Mn and Fe inerease by 0. 6, 0.5, and 0. 3 times respectively compared with the ground group. To conclude, in the space group the contents and proportions of the mineral elements are improved and optimized. X-ray fluorescence spectrum analytic method has many advarrtages, such as quickness, simplicity, high sensitivity, wide measure range, etc. The method can be used for quantitative element analysis and study of Chinese herbal medicines.
