„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.“

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