What is it about?
This study surveyed 57 wild Sicilian oregano samples, combining agronomic taxonomy with detailed phytochemical profiling. Non‑volatile extracts and essential oils were characterized using LC/MS and GC‑FID/GC‑MS, and samples were grouped by cluster analysis. Antioxidant activity was assessed using multiple in vitro assays.

Why is it important?
By linking morphology, chemistry, and antioxidant assays, the work clarifies the chemical diversity of wild oregano populations. This supports better selection of biotypes and improves understanding of variability in essential oils and polyphenolic extracts.
Perspectives
The findings are based on in vitro assays and compositional analyses, which capture chemical diversity rather than biological efficacy in vivo. Environmental factors and genetic background likely contribute to the observed variability. Future work could integrate genomics or standardized cultivation to refine chemotype selection.
