[Naphtha analysis of different processed products of Rhizoma Curcumae from Guangxi by GC-MS].Zhong Yao Cai. 2009 Mar; 32(3):339-42.ZY
To approach the naphtha analysis of different processed products of Rhizoma Curcumae from Guangxi.
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.
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.
Six samples of Rhizoma Curcumae are significantly different in quality,and the naphtha's content of the sample processing with vinegar is the highest.
