Hepta‐and nonadecene from marine fish

Abstract
Two monoalkenes were detected in gizzard shad (Clupanodon punctatus) and sardine (Sardinops melanosticta) by gas chromatography and were identified by combined gas chromatography-mass spectrometry of their cyclic boronate and dioxolane derivatives ascis-6-n-heptadecene andcis-8-n-nonadecene.
