Stachys lavandulifolia Populations: Volatile Oil Profile and Morphological Diversity

The morphological and essential oil diversity of Stachys lavandulifolia populations from the west northwest Iran were evaluated. results showed a significant difference between for nearly all evaluated traits. broadest variation ranges recorded auxiliary shoot length, leaf length in main branch, number flowers inflorescences. Furthermore, cluster analysis divided 13 into four separate groups. GC/MS verified presence 28 components comprising up to 94/4% oils. dominant constituents α-pinene (1.07–34.87%), (E)-caryophyllene (0.45–25.99%), germacrene D (3.36–20.61%), Δ-cadinene (2.82–19.90%), bicyclogermacrene (1.72–12.08%) α-terpineol (0–11.86%), α-muurolol (0.31–11.50%), p-cymene (0.67–9.67%), β-elemene (0.63–9.31%), sabinene (0.32–6.29%). revealed that natural habitats related geo-climatological cues influenced traits composition. Considering substantial environmental variations broad diversity, there would be rich selection pool interest. are step forward breeding programs highlighted needed by pharmaceutical industries. with future comparative study Iranian territories neighboring countries, we will have realistic idea coming conservational exploitation programs.
