| Abstract: | Object To investigate the feasibility that Rhizoma Dioscoreae in different areas was identified by thermal analysis Methods By comparison of the figures for the character of the DTA and DTG curves in N 2 and air environment, Rhizoma Dioscoreae from five areas was identified Results The DTA and DTG curves of varied Rhizoma Dioscoreae were different from each other Conclusion The method can be used in the identification of a variety of Rhizoma Dioscoreae from different areas |
