This study explores the relationship between environmental factors and the main essential oil components in the leaves of Crimean juniper (Juniperus excelsa M. Bieb.), which is commonly distributed in rocky and stony land with shallow soil conditions in the Mediterranean region of Turkey. After the leaf samples collected from 20 plots were dried, essential oil components were detected by GCMS method. α-Pinene (81.3%), myrcene (5.2%) and limonene (4.5%) were found to be the major components, respectively. Relations between these major components and environmental factors (physiographic, climatic and soil factors) were questioned by Pearson correlation analysis, cluster analysis and principal component analysis. According to statistical analysis results; α-pinene bio18, altitude and pH were found to have a negative relationship. The limonene component showed a negative relationship with latitude and clay, but showed a positive correlation with pH.
