title: [Naphtha analysis of different processed products of Rhizoma Curcumae from Guangxi by GC-MS].
abstract: OBJECTIVE
  To approach the naphtha analysis of different processed products of Rhizoma Curcumae from Guangxi.
  
  
  METHODS
  The naphtha was extracted by steam distillation. The relative content of every compound was determined with area normalization method and the structures were elucidated by GC-MS technique.
  
  
  RESULTS
  33 kinds of chemical compositions were identified in the naphtha of the six samples,the main contents were Cyclohexane, 1-ethenyl-1-methyl-2,4-bis (1-methylethenyl)-, 5-Benzofuranacetic acid, 6-ethenyl-4,5,6,7-terahydro-3, 6-dimethyl-alpha. -methylene-,methyl ester, and so on.
  
  
  CONCLUSIONS
  Six samples of Rhizoma Curcumae are significantly different in quality,and the naphtha's content of the sample processing with vinegar is the highest.
