In this study, four sites were chosen in the habitat of the plant which are located in Kashan. In order to complete phytochemical studies during flowering in each site, leaves were collected and after extraction of essential oils by simultaneous method of distillation and extraction using organic solvents, an analytical chromatography connected to a mass spectrometer (GC/MS) was used to identify the ingredients of essential oils. The results of the efficiency of leaves showed in different sites that the highest quantity belonged to the samples taken from sites 2 and 4. Comparison of essential oil compounds showed that the main compounds identified in all the leaf samples from all sites were compounds such as hexadecanoic acid.
