Ethanolic extract of Commiphora myrrha gum-resin promotes therapeutic compound accumulation in Achillea fragrantissima under in vitro culture

Distinct tissue-specific patterns emerged, shoot tips accumulated a wider range of aromatic and therapeutic compounds, whereas callus tissue was enriched in fat-ty acids. These findings suggest that <i>C. myrrha</i> extract functions as a natural biostimulant and elicitor, providing a sustainable approach for producing metabolite-rich <i>A. fragrantis-sima</i> material with potential pharmacological applications.
