What is it about?
This study surveys 57 wild rosemary samples collected across Sicily and characterizes them from both morphological and phytochemical perspectives. Nonvolatile extracts and essential oils were analyzed using chromatographic techniques, and samples were grouped by morphology and chemical profiles. Antioxidant activity was assessed using multiple in vitro assays.

Why is it important?
The work highlights the chemical diversity of wild Rosmarinus officinalis L. and shows that both extracts and essential oils display measurable antioxidant and free radical‑scavenging activity. It supports the value of biodiversity‑driven screening to identify plant biotypes with distinct phytochemical profiles.
Perspectives
The analyses are based on in vitro assays, which do not directly translate to biological effects in vivo. Morphological traits were highly similar across sites, suggesting limited area dependence. Future studies could explore environmental drivers of chemical variability and functional relevance in applied contexts.
