The 28 lemon balm accessions analyzed in this study comprised two subspecies, officinalis (MOFF) and altissima (MALT). They were planted in March 2008 at the Leibniz Institute of Plant Genetics and Crop Plant Research (IPK) in Gatersleben, Germany, and then harvested in June and August 2013. To procure samples, the plants were dried, separated into leaves and stems, and then hydrodistilled. Gas chromatography/mass spectrometry (GC/MS) and…
