Juniperus communis L. from the plants growing in Iran and in the highlands in the valleys of Gorgan hall altitude pass, Hezarjarib and Talysh Spill distributed. In this study, the quality and quantity of active ingredients (extracts) J. communis aerial parts of the plant in different habitat Hezarjarib in behshahr was summer pastures. Branches covering height in 1950, 2050, 2150 and 2250 meters above sea level collected then dried in the open air under the shade. Extract of aerial parts of the plant as meo h-Extract (methanol) to identify compounds extracted from the extract by GC / MS were used. Data analysis was done using SPSS software to analyze and compare the characteristics of an extract from the analysis of variance (ANOVA) and T-test was used. 41 combined extract of aerial parts of the plant were identified, among which compounds are &alpha-pinene, sabinene, limonene, &beta- cubebene and diallyl phthalate, and also has the highest percentage of sites significant effect on the composition of phthalate diethyl and &beta-thujene in extract has branches. Compounds abieta-8,11,13-triene, d- (+) - carvone, hexadecanamide, elemol and trans sabinene hydrate were found only in one locality. Also, a significant correlation was observed between 12 combination with some soil elements.
