X-ray fluorescence spectrum (XRF) analytic method was applied to the determination of the contents and varieties of mineral elements in the space flight mutagenesis breeding scutellaria baicalensis Georgi, and compared with the ground group which were planted and collected together under the same conditions, in an attempt to search for the influence of space environment upon mutation on scutellaria baicalensis Georgi. The result indicates that the varieties of the main mineral elements in the two samples are samely basically, therefore, the two samples have same absorption and enrichment capability of specific element, but the contents of elements Ca, Na, Zn and S increase by 0.3, 0.3, 0.04 and 0.7 times, respectively, in the space group. This modern testing method played an important role in the study. It is recommended that the testing method should be used in the selection of space bred herbal seeds for its advantages, such as quick, simple, highly sensitive, and of wide measure range. To conclude, New breeds can be selected by space breeding, it is significant for the selection and growing of space herbal medicine seeds, and it also has broad application in space breeding of medical plants.
