[Chemical components of essential oils from the herb of Ligularia virgaurea].
OBJECTIVE
To provide the foundation for reasonable utilization by analyzing the essential oils of Ligularia virgaurea.


METHODS
The essential oils were extracted by using steam distillation and separated with GC capillary columns. The components were quantitatively determined with normalization method, and were identified with GC-MS.


RESULTS
41 components were identified, which took up 72.73% of the essential oils.


CONCLUSIONS
The main components of essential oils were 4-methyl-1-(1-methylethyl)-3-cyclohexen-1-ol(14.369%), crotonic acid, 2,2-dimethyl-butanoic acid, 1-methyl-3-(1-methylethyl)-benzene, (1s-endo)-1,7,7-trimethyl-bicyclo[2,2,1]heptan-2-ol, trans-1-methyl-4-(1-methylethyl)-2-cyclohexen-1-ol, alpha-cadinol and alpha,alpha,4-trimethyl-3-cyclohexene-1-methanol.
