用气相色谱-质谱（GC-MS）方法分析了6种双维管束松亚属树种:赤松（Pinus densiflora Sieb.etZucc.）、黑松（P.thunbergii Parl.）、油松（P.tabulaeformis Carr.）、巴山松（P.henryi Mast.）、黄山松（P.taiwanensis Hayata）、马尾松（P.massoniana Lamb.）和2种单维管束松亚属树种:白皮松（P.bungeana Zucc.）及红松（P.koraiensis Sieb.et Zucc.）的种子油脂肪酸成分。结果表明这8种松属植物的种子油脂肪酸成分有相似的分布情况:最主要成分都是亚油酸C_{18:2（9,12）};都同时含有3种Δ⁵的不饱和脂肪酸:C_{18:2（5,9）},C_{18:3（5,9,12）}和C_{20:3（5,11,14）}。这两个特征可以作为松属（Pinus L.）的化学分类证据。结果还表明同一属内各种间的种子油脂肪酸成分无明显差别。

The fatty acids from the seed oils of 8 species of Pinus L. (Pinaceae) : 6 species of diploxylon (P. densiflora Sieb. et Zucc. , P. thunbergii Parl. , P. tabulaeformis Carr. , P.henryi Mast. , P. taiwanensls Hayata. , P. massoniana Lamb. ) and 2 species of haploxylon (P. bungeana Zucc. , P. koraiensis Sieb. et Zucc. ) have been analyzed by GC-MS. Our results showed that the distributions of fatty acids from the seed oils in all these 8 species are very similar: the dominant component is linoleic acid C_18︰2(9,12) ；there are three kinds of Δ⁵unsaturated fatty acids C_18︰2(5,9) , C_{18︰3(5,9,12)} , C_{20︰3(5,11,14)} simultaneously. These characters can be used as the chemotaxonomic informations for Pinus L. There are no significant differences of fatty acid compositions among the various species in the same genus.
