    Abstract:
    In this paper, GC-MS and pressurized liquid extraction (PLE) was developed for identification and quantitative determination/estimation 11 sesquiterpenes including germacrene D, curzerene, gamma-elemene, furanodienone, curcumol, isocurcumenol, furanodiene, germacrone, curdione, curcumenol and neocurdione in Ezhu which are derived from three species of Curcuma, i.e., Curcuma phaeocaulis, Curcuma wenyujin and Curcuma kwangsiensis by using an analogue as standard. The results showed the methodology could quantitatively compare the quality of three species of Curcuma. The contents of investigated sesquiterpenes in three species of Curcuma were high variant. Hierarchical clustering analysis based on characteristics of 11 identified peaks in GC profiles showed that 18 samples were divided into two main clusters, C. phaeocaulis and C. wenyujin, respectively. C. kwangsiensis showed the characters closed to C. phaeocaulis or C. wenyujin based on its location. Five components such as furanodienone, germacrone, curdione, curcumenol and neocurdione were optimized as markers for quality control of Ezhu.
