【摘要】Objective:To examine the chemical variability in inflorescences of

wild

populations

of

Stachys

lavandulifolia

Vahl(S.lavandulifolia)collected throughout two provinces(lsfahan and Chaharmahal va Bakhtiary),Southwest Iran.Methods:The essential oils of S.lavandulifolia Vahl from seven locations were obtained by hydro-distillation

and

analysed

by

gas

chromatography

and

gas

chromatography-mass spectrometry.Results:The results revealed that distinct differences in the content of compounds depending on region of sample collection.The main constituents of the essential oils wereα-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%),△-cadinene(trace to 11.6%)and 1,4-methano-1 H-indene(trace to 10.1%).Conclusions:The 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.
