Drying (or dehydration) is the most important phases after producing medicinal plant that have an important role on the quantity of their effective materials. Experiments were carried with random plan form by 3 replications in 2011 and 2012. The object of study was to investigate the effect of different drying methods on medicinal plant essence compounds and percentage such as Lippie citriodora. Drying (or dehydration) treatments including drying in the shade for two days (traditional method) and drying by artificial method includes semi-industrial dryer (including metal plates and warm air flow) for 2 days in 40ċ and industrial dryer (oven) in 50ċ for 48 hours. Obtained essence of different drying treatments and taking essence by gas chromatograph GC and gas chromatograph linked to Mass spectroscopy GC/MS were investigated in this study. The numbers of compounds were defined in the citriodora plant essence. The highest rate of Spathulenol (%25.18 in first year and 26.2% in second year) was obtained in semi-industrial drying treatment. According to the present study it should be mentioned that main constituents of essence and there was significant variance in each compounds rate. The highest percent of essence observed in drying treatment by semi industrial method (%3.13 in first year and 4.12% in second year). For number of essence extracts, there were no any significant differences between methods.
