To discuss the relationship between metallic element and disease through determine the elementals in Tibetan Herbal Medicines and Tibetan Medicine Preparations that have obvious effect on hepatobiliary diseases by Synchrotron Radiation X-ray Source, then to reveal the substance foundation of pharmacological action. The results show that all the Tibetan Herbal Medicines used in the experiment have the 9 kinds of metallic elements of potassium(K), calcium(Ca), titanium(Ti), vanadium(V), chromium(Cr), manganese(Mn), ferrum(Fe), zinc(Zn) and lead(Pb), the content of the elements are in the ppb or ppm level though the element constitute and the content have obvious difference. Tibetan Medicine Preparations have another 6 kinds of metallic elements of nickel(Ni), copper(Cu), rubidium(Rb), mercury(Hg), cobalt(Co), gallium(Ga) and 1 kind of nonmetallic elements of arsenic(As) when compare with Herbal Medicines, and the element constitute and the content also have obvious difference. Take advantage of SR-XRF, the test gets the basic data of elements of Tibetan Herbal Medicines and Preparations, supply the scientific support to discuss the interaction of pharmacological mechanism and the metallic elements, and find the suitability of the technique for the metallic elements detection in Tibetan Medicines.
