Abstract :
In this research, due to investigation the effect of extraction time on essential oil composition of 4 genotype of Rosa damascene Mill., the petals of four genotypes of this plant were collected from Rose fields (1320m) of Research Institute of Forest and Rangelands -Tehran. Essential oils were obtained for 30-150 minutes by hydro- distillation method (Clevenger apparatus) and were analyzed by GC and GC/MS. The results were showed that the major common components included: citronelol (59%), geraniyol (25.8%) and linalool were higher than other genotype in Semnan and the best time for extraction was 90 minutes.
