Abstract:
OBJECTIVETo examine the chemical variability in inflorescences of wild populations of Stachys lavandulifolia Vahl (S. lavandulifolia) collected throughout two provinces (Isfahan and Chaharmahal va Bakhtiary), Southwest Iran.
METHODSThe essential oils of S. lavandulifolia Vahl from seven locations were obtained by hydro-distillation and analysed by gas chromatography and gas chromatography-mass spectrometry.
RESULTSThe results revealed that distinct differences in the content of compounds depending on region of sample collection. The main constituents of the essential oils were α-thujone (0.3%-32.3%), α-pinene (trace to 37.3%), myrcene (0.5%-15.9%), β-phellandrene (1.1%-37.9%), germacrene D (0.4%-11.3%), Δ-cadinene (trace to 11.6%) and 1, 4-methano-1 H-indene (trace to 10.1%).
CONCLUSIONSThe results of the present study indicated that essential oil components of S. lavandulifolia Vahl can be varied with genetic (ecotype), environmental conditions and geographic origin. In general, the essential oils of various populations of S. lavandulifolia Vahl were rich in monoterpenoids and sesquiterpenoids.
