Introduction and Background: Climatic condition is one of the most important determinants of the qualitative properties of essential oils produced by Rosa damascena Mill and play a decisive role in the quality of essential oil extracted from it.
Aims: The main objective of this study is to investigate the comparison of the different composition of the essential oils in the present conditions and under climate changing conditions.
Methodology: In this study, data related to quantitiy features and Rosa damascena Mill essence composition value were sampled from 6 orchards and extracted in labratoary .8 main compositions –called Benzene, ethanol, citronellol, geraniol, eugenol, methyl eugenol, Heptadecane, Nonadkan, and Hnykozan were identified from extracted essence of these orchards. Finally, correlation analysis were used to revealing the association among climatic factors and extracted Essense composition of each orchard.
Conclusion: The results showed that 8 extracted compositions formes more than average 0.88 of sampled flowers essence and generally Citronellol, geraniol and Nonadkan form the highest percent of essence. the results also showed that of 8 important compositions of Rosa damascena Mill. essence m changes in 4 compositions Nonadkan, benzene, ethanol and Geraniol and methyl eugenol meaningfully are dependant on space- changes in weather factors from March to June and specially April. concentration of two compositions Benzene, ethanol and methyl eugenol in all sampled orchards in simulated climate 2050 have increased from 2014. While concentration of two chemical compositions Nonadkan and Geraniol in 2050 had meaningfully decreased rather to 2014
