The polysaccharide was measured by phenol-sulfuric acid colorimetric method. According to the method from Chinese pharmacopoeia, the contents of extraction and total ashes were measured. The result showed that the contents of polysaccharide, extraction,total ashes and trace elements were different in astragalus from different producing areas. The contents of extraction and total ashes in Shandong astragalus were the highest and the content of polysaccharide in shanxi geo-authentic astragalus was the highest among all the areas tested. Trace elements were the highest of Shanxi geo-authentic astragalus .
