Zusammenfassung: <jats:title>Abstract</jats:title><jats:p>The essential oil obtained by hydrodistillation from the aerial parts of <jats:italic>Aristolochia delavayi</jats:italic> <jats:sc>Franch.</jats:sc> (Aristolochiaceae), a unique edible aromatic plant consumed by the Nakhi (Naxi) people in Yunnan, China, was investigated using GC/MS analysis. In total, 95 components, representing more than 95% of the oil composition, were identified, and the main constituents found were (<jats:italic>E</jats:italic>)‐dec‐2‐enal (52.0%), (<jats:italic>E</jats:italic>)‐dodec‐2‐enal (6.8%), dodecanal (3.35%), heptanal (2.88%), and decanal (2.63%). The essential oil showed strong inhibitory activity (96% reduction) of the production of bacterial volatile sulfide compounds (VSC) by <jats:italic>Klebsiella pneumoniae</jats:italic>, an effect that was comparable with that of the reference compound citral (91% reduction). Moreover, the antimicrobial activity of the essential oil and the isolated major compound against eight bacterial and six fungal strains were evaluated. The essential oil showed significant antibacterial activity against <jats:italic>Providencia stuartii</jats:italic> and <jats:italic>Escherichia coli</jats:italic>, with minimal inhibitory concentrations (<jats:italic>MIC</jats:italic>) ranging from 3.9 to 62.5 μg/ml. The oil also showed strong inhibitory activity against the fungal strains <jats:italic>Trichophyton ajelloi, Trichophyton terrestre, Candida glabrata, Candida guilliermondii</jats:italic>, and <jats:italic>Cryptococcus neoformans</jats:italic>, with <jats:italic>MIC</jats:italic> values ranging from 3.9 to 31.25 μg/ml, while (<jats:italic>E</jats:italic>)‐dec‐2‐enal presented a lower antifungal activity than the essential oil.</jats:p>
