The constituents of volatile oils from Thymus altaicus

Abstract

The volatile oil constitutes were extracted from the aerial parts of Thymus altaicus by water steam distillation were analyzed by GC-MS method. Fifty six compounds were separated. Their relative contents were determined by area normalization in which 47 volatiles were identified. The major volatile oils of T. altaicus are 3- cyclohexene-1-methanol, α,α-4-trimethyl- (35.84%), benzene, 1-mehtyl-2-(1- methylethyl)-(15.24%), β-myrcene (10.30%), thymol (7.94%), 1,4-cyclohexadiene, 1-methyl-4-(1-methylethyl)-(5.34%), caryophyllene (5.26%), 1,6-octadien-3-ol,3,7-dimethyl (4.78%), 2,6-octadien-1-ol,3,7-dimethyl-, (E)- (2.06%), 2,6-octadien-1-ol, 3,7-dimethyl-, acetate, (E)- (1.31%), caryophyllene oxide (1.23%).
