Abstract: To detect the calcium carbonate and IR in marine-derived shell TCM,and then compare the contents of calcium carbonate and IR in the three herbs from different areas to provide scientific basis for the quality evaluation and qualitative identification of the three herbs. The content of calcium carbonate was detected by EDTA titrimetric method;applying IR to analyses the chemical composition difference of marine-derived shell TCM from different areas. The calcium carbonate content of Clam Shell was ranged from 79.74% to 98.34%. The calcium carbonate content of Os Sepiae was ranged from 81.07% to 94.51% and the calcium carbonate content of oysters was ranged from 66.71% to 96.92%. The IR analysis shows that Clam Shell、Os Sepiae、oysters were all consisted of the major Calcium carbonate and a slight amount of organisms. There are no significant differences among the contents of calcium carbonate and IR of Clam Shell、Os Sepiae and oysters from different areas. It fails to reflect the inner quality and work on qualitative identification of the three herbs on the whole with the content of calcium carbonate and IR.

Key words: marine-derived shell TCM, EDTA titrimetric method, FTIR
