| Abstract: | A RigaKu 3070 X-ray spectrometer was applied to the determination of mineral elements in Astragal, and calibration made by using national plant standard reference materials. The precision parameter, RSD (n=10) of mineral elements in Astragal prepared by method is 0.2% to 12%. This result identical with GBW07602, GBW07603, GBW07605, that obtained from national plant standard reference material. This result was also similar with the mineral elements content in Astragal of other area determined by this method. |
