摘　　要：通过研究白皮松松脂的化学特征，得出它含有２５个主要组分，其中单萜类化合物含量很高，占４６４％，尤其β蒎烯的含量高达２４８％。同时，与单维管束和双维管束松亚属１６种松树松脂比较分析，发现白皮松松脂在异海松酸、长叶松酸／左旋海松酸、糖松酸和枞酸等树脂酸含量与单维管束松树不同，而与双维管束松树相似。这一结果为建立白皮松亚属提供一个重要依据。The chemical characteristrics of oleoresin from Pinus bungeana Zucc. was studied. It contains 25 contents. The amount of its monoterpenes is about 47.0% and that of β pinene is as high as 24.8%. The chemical compositions of oleoresins of 16 species from subgen. Strobus and subgen. Pinus were also analyzed by GC and GC MS. The amounts of isopimaric acid, palustric acid/levopimaric acid,lambertianic acid and abietic acid in P.bungeana oleorensin differ from that of subgen. Strobus, and is similar to that of subgen. Pinus.
