✦ Synopsis

Mentha  piperita L. shoot tip and ®rst leaf pair were fed with aqueous solutions of deuteriumlabelled racemic piperitone and achiral piperitenone. The essential oil was extracted by solid phase microextraction (SPME) and subsequently analyzed using enantioselective multidimensional gas chromatography/ mass spectrometry (enantio-MDGC±MS). Both labelled precursors led to the corresponding 1R-con®gured p-menthan-3-ones (À)-menthone and ()-isomenthone, favouring the labelled ()-isomenthone.
