Abstract: Volatile oil was isolated Coriandrum sativum leaves and stem with steam distillation,and then its components were identified by capillary GC-MS method. Results showed that there are 79 volatile components in the oil accounting for 97.63% of the total area of the peaks. The relative contents of the constituents were determined by area normalization method.The main volatile compounds in the oil are cyclohexanone,2-tridecenal(E),dodecanal,á-linalool,menthofuran,1,5-diphenyl-3-(2-phenylethyl) -2-pentene,tetradecanal,sarcostin ketone,3-phenyl-2-butanol,decanal,2-dodecenal,cinnamyl-á-phenylpropionate,3-hexen-1-ol,acetate,2-dodecenal,4-bicyclo[2.2.1]hept-5-en-2-yl-1,1-diphenyl-2-pentyne-1,4-diol,hexadecanoic acid,ethylbenzene,cis-3-hexenyl lactate,3-hexen-1-ol,formate,mandelonitrile benzoate and 3-hexenyl formate.
