用抽气吸附法收集落叶松球果挥发性气味物质，通过ＧＣ─ＭＳ测定其主要气味的化学成分与含量，结果表明：α－蒎烯、β－蒎烯、月桂烯、β－罗勒烯、水芹烯、３－蒈烯的含量在健康球果与受害球果气味成分上有明显差异。
The volatile components of larch cones were collected by air suction method. The chemical components and contents of larch cones were determined by GC-MS. The results showed that the main constituents of larch cones were α-pinene, β-pinene, myrcene, Phellandrene, 3-carene content in healthy cones and condemned cones odor components were significantly different.
