Abstract The volatile constituents of Senecio glaucus subsp. coronopifolius (Maire Alexander) were investigated by capillary GC‐MS of the essential oil obtained by steam distillation and of the headspace. Out of more than 80 volatiles, 30 components, accounting for 90% of the oil, were identified by their Kováts indices on stabilized OV‐1 columns and mass spectral data. Chief components of the oil are: myrcene (24%) and dehydrofukinone (I) (21%). (I) was isolated and characterized by UV, IR, 1 H‐NMR, 13 C‐NMR and MS. The oil smells apricot‐like, while the odour of the intact plant is herbaceous, spicy and floral fruity. (I) is the character impact compound of the oil.
