In the flora of Iran, genus Stachys is represented by 34 species while its number is about 300 species in the world. Stachys fruticulosa, with the local name of Sonbole gachdust, is grown in many parts of Iran, Iraq, and Anatolia, and is used as an anti-inflammatory agent in traditional medicine (1). Salvia lavandulifolia is known as mountain tea (Chaye-kuhi in Iran) and its English name is Betony. In addition, it is used as the herbal tea in gastrointestinal disorders (2). The hydrodistillation of the aerial parts of S. palaestina collected in Lebanon yielded 0.1% (w/w) of EO. Gas chromatography (GC) and GC-mass spectrometry (MS) analyses enabled the identification of 87 compounds representing 90.8% of the total oil. Hexadecanoic acid (10%), hexahydrofarnesyl acetone (6.9%), eugenol (4.3%), and (E)-caryophyllene (4.3%) were the main components (3). According to another report (4), the water distilled EO of the aerial part of S. pubescence was rich in fatty acids like hexadecanoic and linoleic acids in addition to benzaldehyde and spathulenol whereas the steam distilled oil of the plant contained hexadecanoic acid, spathulenol, and eugenol. Both oils were rich in fatty acids (36.6% and 27.9%, respectively). The chemical composition of the EOs from the aerial parts of two endemic Turkish species (i.e., Stachys amanica and S. petrokosmos) was analyzed by GC and GC-MS. The major components of the EO of S. amanica in Dadagli were found to be α-pinene, α-bisabolol, (E)β-caryophyllene, and germacrene D. However, the EO from S. amanica in Basyurt contained α-pinene, β-pinene, and (E)-β-caryophyllene. On the other hand, the major components of the EO from S. petrokosmos in Dadagli were reported as α-pinene, α-bisabolol, α-zingiberene, (E)-β-caryophyllene, and γ-curcumene. Moreover, the EO from S. petrokosmos in Belen included α-pinene, γ-curcumene, α-bisabolol, 16-kaurene, and α-zingiberene (5). In another study (6), characterization by the GCflame ionization detector and GC/MS analyses of the S. officinalis EO obtained by the hydrodistillation of the aerial parts allowed the identification of 190 components that represented 97.9% of the total oil content. The main identified constituents were germacrene D (19.9%), β-caryophyllene (14.1%), and α-humulene (7.5%). A
