„Variation in scent chemistry of both Platanthera bifolia and P. chlorantha was considerable: different scent chemotypes were found among individuals as well as populations. Mainly linalool, lilac aldehydes and alcohols, geraniol, and methyl benzoate distinguished the chemotypes.“
[Fragrance chemotypes of Platanthera (Orchidaceae)‐the result of adaptation to pollinating moths?., Tollsten, L., Bergström, L. G., Nordic Journal of Botany, Vol.13(6), 1993, 607-613]

„Although the German popular name 'Waldhyacinthe' (wood hyacinth) and many literature sources ascribe a hyacinth-like scent to this orchid, it is more reminescent of certain lily nd honeysuckle species and, in very general terms, posesses a basic scent concept of the 'white-floral' type.“
This scent is mainly attributable to linalool (18.8% of the headspace), methyl benzoate (58.0%) and methyl salicylate (2.4%), with special significance ascribed to the trace components like lilac aldehydes, lilac alcohols and their acetates, cinnamic aldehyde, geraniol, eugenol and vanillin.

Electrophysiologically active compounds from P. bifolia flowers are benzyl benzoate, benzyl salicylate, cinnamyl alcohol, lilac aldehydes, methyl benzoate and methyl salicylate.

Flowers of P.bifolia subsp. osca from Italy were characterized by the absence of perceptible volatile emissions during the day while in the night a strong and pronounced aroma was developed. Main components of the flower scent of four samples of P. bifolia subsp. osca collected (DVB/CAR/PDMS) at Pignola were lilac aldehydes (3.6-13.6%) and lilac alcohols (25.0-61.5%), linalool (0-10%) and alkanes. Platanthera bifolia subsp. osca sample collected at Grisolia showed as main components linalool (17.8%), benzyl benzoate (55.8%), and benzyl salicylate (6.7%). Benzyl benzoate (74.7%), methyl benzoate (9.0%), geraniol (4.0%), and benzyl salicylate (3.2%) were the main volatiles of P. bifolia subsp. osca collected at Palena.
