GC–MS/MS Profiling of the Essential Oil from Algerian Phlomis herba‐venti L. subsp. pungens: A First Report

This work constitutes the first comprehensive investigation of the essential oil composition from the aerial parts of Phlomis herba‐venti L. subsp. pungens , collected in Algeria. The essential oil was extracted by hydrodistillation and subsequently analyzed using gas chromatography–tandem mass spectrometry (GC–MS/MS). A total of 57 constituents were identified, representing 99.96% of the total oil content. The predominant compounds were (–)‐germacrene D (33.03%), β‐caryophyllene (14.24%), β‐bisabolene (10.53%), and δ‐cadinene (4.35%), mainly belonging to the sesquiterpene class. This detailed chemical characterization provides a foundational basis for future studies focused on the biological and pharmacological evaluation of this essential oil.
