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