Abstract: To compare the differences of essential oils extracted from Curcumae Rhizoma with different origins. The TIC of the essential oils of Curcumae Rhizoma from three different origins recorded by CP(2010) , were investigated by GC-MS combined with automated mass spectral deconvolution and identification system(AMDIS),steps as follow： firstly, overlapped peaks were resolved by AMDIS,secondly, NIST11.L standard MS spectral database combined with retention index were used to assist qualitative analysis, thirdly, the peak area of each split peak were determined by choosing the characteristic fragment ion peak, finally, the relative percentage contents of each compounds were determined through peak area normalization method. The results showed that the components of the essential oils of Curcumae Rhizoma from three origins were different from each other at various degree. In conclusion, the types and content of essential oils could be an indicator to evaluate the quality of Curcumae Rhizoma from different origins and its geoherbalism.
