Oyster leaf (Mertensia maritima), also called vegetarian oyster, has a surprising oyster-like aroma. Its volatile composition was investigated here for the first time. In total, 109 compounds were identified by gas chromatography–mass spectrometry (GC-MS) and quantified by GC-FID. The use of GC–olfactometry on both polar and nonpolar columns allowed the detection of the molecules having an oyster-like, marine odor. Four ...
