Aim:The purpose of this study is to develop a method to explore the difference between the rhizomes and tuberous roots of Curcuma longa, and screen out the difference markers. Materials and Methods: The quantitative analysis and fingerprints of rhizomes and tuberous roots were established by HPLC, rhizomes and tuberous roots of Curcuma longa were clearly discriminated by Hierarchical Cluster Analysis (HCA), Similarity Analysis (SA) and Principal Component Analysis (PCA). The difference markers were screened out by Orthogonal Partial Least Squares Discriminant Analysis (OPLS-DA). Results: The contents of curcumin, bisdemethoxycurcumin and demethoxycurcumin in all rhizomes were higher than those in tuberous roots. Multivariate statistical analysis shown that the samples of rhizomes were grouped into the same categories and samples of tuberous root were grouped another group in each analysis mode. And the OPLS-DA model had a good productivity and good fit indicated by the value of R 2 Y=0.981, Q 2 =0.946and R 2 X=0.816. The important markers for discrimination samples were the peak 14, peak 10 (demethoxycurcumin) and peak 11 (curcumin). Conclusion: The fingerprinting combination of multivariate statistical analysis can be applied to distinguish the rhizomes and tuberous roots of Curcuma longa.

The Temperature-jump/FTIR (T-jump/FTIR) spectroscopy was introduced to resolve the decomposition kinetics parameters of [Cd(CHZ) 3 ](ClO 4 ) 2 (CdCP) at high temperature following very rapid heating process. The increase in the absorbances during the flash pyrolysis of CdCP yielded the kinetics parameters in the range of 360-430 ℃ at 0.1 MPa Ar atmosphere: E a ＝28.6 kJ/mol and ln A＝17. The kinetics parameters of the exothermic decomposition reaction were also determined by using DSC method. The value of E a determined by T-jump/FTIR spectroscopy is smaller than that by Kissinger method and Ozawa-Doyle method, which makes these values qualitatively consistent with other energetic materials. The T-jump/FTIR spectroscopy might be resembled as the surface of explosion reaction very closely. In addition, the decomposition kinetics of evolution of the major four individual gas products was also resolved by T-jump/FTIR spectroscopy, which might be essential for detailed combustion modeling of solid energetic materials.
