松树的单个成分。从七个地中海种群中分离的油不皂化物被鉴定和定量。P. pesticides油不皂化物含有非常高水平的植物甾醇（>或=4298 mg kg-1的总提取脂质），其中β-谷甾醇是最丰富的（74%）。脂肪醇含量为1365毫克公斤-1的总提取的脂质，其中二十八烷醇是最丰富的（41%）。两种醇（二十六烷醇和二十八烷醇），这通常是不存在于普通植物油中，被描述为P. pesticides油。有几乎没有差异，总的不皂化物的七个地中海人口的研究。然而，甾醇和脂肪醇的含量表现出一定的变异性，突尼斯和摩洛哥人口表现出非常不同的和更高的含量。
Individual components of Pinus pinea L. oil unsaponifiable matter isolated from seven Mediterranean populations were identified and quantified. P. pinea oil unsaponifiable matter contained very high levels of phytosterols (>or=4298 mg kg-1 of total extracted lipids), of which beta-sitosterol was the most abundant (74%). Aliphatic alcohol contents were 1365 mg kg-1 of total extracted lipids, of which octacosanol was the most abundant (41%). Two alcohols (hexacosanol and octacosanol), which are usually absent in common vegetable oils, were described for P. pinea oils. There were almost no differences in the total unsaponifiable matter of the seven Mediterranean populations studied. However, sterol and aliphatic alcohol contents showed some variability, with Tunisian and Moroccan populations showing very different and higher contents.
