Abstract:

The chemical characteristrics of oleoresin from Pinus bungeana Zucc. was stud-
ied. 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 sub-
gen. 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.
