„Oyster leaf (Mertensia maritima) has a weak odor, but when scratched, it has first a green, slightly mushroom odor, followed by some surprising marine, oyster-like notes. When eaten, the retronasal aroma is extremely reminiscent of oyster. This explains why oyster leaf is also called vegetarian oyster…
The use of GC−olfactometry on both polar and nonpolar columns allowed the detection of the molecules having an oyster-like, marine odor. Four compounds were identified and confirmed by synthesis: (Z)-3-nonenal, (Z)-1,5-octadien-3-ol, (Z,Z)-3,6-nonadienal, and (Z)-1,5-octadien-3-one. After evaluation of freshly prepared reference samples, these compounds were confirmed to be reminiscent of the oyster-like marine notes perceived in the tasting of cut leaves.“
