通过银离子 TLC 对其 FAME 和 GLC 结合 MS 对其吡啶衍生物进行表征，对来自 Hesperopeuce mertensiana（松科裸子植物）种子油的次要罕见 FA 进行了表征。这些不常见的成分具有以下结构：16-甲基八碳烯酸（反异 19:0）、16-甲基-顺-9-八碳烯酸（反异-19:1）和 16-甲基-顺-9,顺-12-十八碳二烯酸（反异-19:2）。这些支链 C-19 酸较早在云杉木材中被发现，这表明这些酸可能广泛存在于松科脂质成分中，尽管数量很少。
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-methyloctaclecanoic (anteiso-19:0), 16-methyl-cis-9-octaclecenoic (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.
