Gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) were used to compare between the essential oil components from needles of Pinus armandii Franch versus P. tabulaeformis Carr., growing on the same site at Taibai Mountain, China. Under optimum extraction and analysis conditions, 65 and 66 constituents each were identified in P. armandii and P. tabulaeformis, which accounted for 87.9% and 87.1%, respectively, of their oils. Based on their terpene compositions, we concluded that these species belong to a high-caryophyllene chemotype, with sesquiterpenes comprising 54.4% to 54.8% of the total contents. We also determined minor qualitative and major quantitative variations in some compounds. Compared with that from P. tabulaeformis, P. armandii oil had more gamma-muurolene (7.5%), terpinolene (5.8%), and longifolene (5.7%). In contrast, alpha-pinene (8.6%) and caryophyllene oxide (7.4%) were the dominant compounds in P. tabulaeformis.
采用气相色谱（GC）和气相色谱 - 质谱联用（GC - MS）技术，对生长于中国太白山同一地点的华山松（Pinus armandii Franch）和油松（P. tabulaeformis Carr.）针叶中的挥发油成分进行比较。在最佳提取和分析条件下，华山松和油松分别鉴定出65种和66种成分，分别占各自挥发油的87.9%和87.1%。基于它们的萜类成分，我们得出结论，这些物种属于高石竹烯化学型，倍半萜占总含量的54.4%至54.8%。我们还确定了一些化合物的微小定性和主要定量差异。与油松相比，华山松挥发油中γ- 依兰油烯（7.5%）、萜品烯（5.8%）和长叶烯（5.7%）含量更高。相比之下，α-蒎烯（8.6%）和石竹烯氧化物（7.4%）是油松中的主要成分。
