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.
