Minor uncommon FA from Hesperopeuce mertensiana (a gymnosperm species of the Pinaceae family) seed oil were characterized through a combination of silver ion TLC of their FAME, and GLC coupled with MS of their picolinyl derivatives. These uncommon components have the structures 16‐methyloctadecanoic (anteiso‐19∶0), 16‐methyl‐ cis ‐9‐octadecenoic (anteiso‐19∶1), and 16‐methyl‐ cis ‐9, cis ‐12‐octadecadienoic (anteiso‐19∶2) acids. These branched C 19 acids were identified earlier in the wood of Picea abies , which would indicate that such acids could be widespread, though minor, components of Pinaceae lipids.
