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 1 6-methyl-cis-9,cis-12-octadecadienoic (anteiso-19:2) acids. These branched C19 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.
通过对来自山地云杉（松科裸子植物物种）种子油中的次要罕见脂肪酸甲酯进行银离子薄层色谱分析，并结合对其吡啶基衍生物进行气相色谱-质谱联用分析，对这些脂肪酸进行了表征。这些罕见成分具有16-甲基十八烷酸（反异-19:0）、16-甲基-顺-9-十八碳烯酸（反异-19:1）和16-甲基-顺-9,顺-12-十八碳二烯酸（反异-19:2）的结构。这些支链C19酸早些时候在欧洲云杉的木材中被鉴定出来，这表明此类酸可能是松科脂质中广泛存在但含量较少的成分。
