species are important in traditional medicine throughout their ranges, and pine essential oils are of interest in aromatherapy and as topical treatments. In this work, the leaf (needle) essential oils of var. and subsp. from Oregon and growing in Idaho, have been obtained by hydrodistillation and analyzed by gas chromatographic techniques. The leaf essential oil of was dominated by β-pinene (21.5-55.3%), methyl chavicol (8.5-41.5%), α-pinene (3.6-9.6%), δ-3-carene (3.6-6.2%), and α-terpineol (1.4-5.3%). The major components of essential oil were β-phellandrene (23.8%), terpinen-4-ol (11.0%). The essential oil of was dominated by α-pinene (37.1%), β-pinene (21.9%), bornyl acetate (12.8%), and camphene (8.5%). Chiral gas chromatography revealed the enantiomeric ratios of α-pinene and limonene to be variable, but (-)-β-pinene predominated in essential oils.
在其分布范围内，物种在传统医学中很重要，松油精在芳香疗法和局部治疗中很有兴趣。在这项工作中，通过水蒸馏法获得了俄勒冈州和爱达荷州生长的 var. 和 subsp. 的叶（针）精油，并通过气相色谱技术进行了分析。 的叶精油以 β-蒎烯（21.5-55.3%）、甲基丁香酚（8.5-41.5%）、α-蒎烯（3.6-9.6%）、δ-3-蒈烯（3.6-6.2%）和α-萜品醇（1.4-5.3%）为主。 的主要成分是β-水芹烯（23.8%），萜品烯-4-醇（11.0%）。 的精油以α-蒎烯（37.1%）、β-蒎烯（21.9%）、乙酸龙脑酯（12.8%）和莰烯（8.5%）为主。手性气相色谱表明 α-蒎烯和柠檬烯的对映体比例是可变的，但（-）-β-蒎烯在精油中占优势。
