In this study, essential oils and variety of chemical compounds of Salvia limbata in flowering stage in different altitudes in July were studied. In order to study the active ingredients of plant in studied sites in flowering stage nine plant samples were examined for phytochemical analysis. Identification of the basic constituents (quantity and quality) with GC / MS and GC-FID (gas chromatography coupled to mass spectrometer) has been done. The yield of essential oils in flowering stage in Paeein Taleghan 0.34% in Mian Taleghan 0.34% and in Bala Taleghan is 0.46%. According to the results, difference in altitudes in three habitats shows a significant difference among the percentages of the obtained compounds. The most important constituents of essential oil include α-Pinene, β-Pinene, allo-aromadendrene and Spathulonol. Also, Salvia is reported as one of the sources for the extraction of α -pinene.
