| The flower fragrance may be characterised as //'aromatic spicy-floral'// with a basic accord consisting of phenylethanol, benzyl alcohol, and benzaldehyde, "...and deriving its pleasant character from a series of minor but olfactorily important components such as citral, cinnamic aldehyde, cinnamic alcohol, eugenol and vanilline. In chemical terms, the scent of Gymnadenia odoratissima is quite closely related to that of [[nigritella_nigra_l._rchb._f|Nigritella nigra]]." \\ | The flower fragrance may be characterised as //'aromatic spicy-floral'// with a basic accord consisting of phenylethanol, benzyl alcohol, and benzaldehyde, "...and deriving its pleasant character from a series of minor but olfactorily important components such as citral, cinnamic aldehyde, cinnamic alcohol, eugenol and vanilline.

| Of 44 volatiles identified in the flower scent, seven were physiologically active in pollinators: Benzaldehyde (8.0% day, 5.7% night), phenylacetaldehyde, benzyl acetate (20.8% day, 17.2% night), 1-phenyl-2,3-butandione (7.6% day, 8.4% night), phenylethyl acetate (24.7% day, 20.8% night), eugenol (4.6% day, 3.1% night), and one unknown compound. Phenylacetaldehyde increased during the night: 9.4% day, 24.7% night - the most pronounced change in odour emission. On GC, vanillin co-eluted with (Z)-isoeugenol (1.9% day, 3.3% night; sum).\\ | Of 44 volatiles identified in the flower scent, seven were physiologically active in pollinators: Benzaldehyde (8.0% day, 5.7% night), phenylacetaldehyde, benzyl acetate (20.8% day, 17.2% night), 1-phenyl-2,3-butandione (7.6% day, 8.4% night), phenylethyl acetate (24.7% day, 20.8% night), eugenol (4.6% day, 3.1% night), and one unknown compound.
