The essential oil composition of the leaves, stem, flowers and roots of Ligusticopsis wallichiana (DC.) Pimenov & Kljuykov were analyzed by GC-FID and GC-MS methods. Forty-five constituents, forming 93.2%-97.8% of the oil compositions, were dominated by acetylenic (31.5%-92.8%) compounds and sesquiterpenoids (0.3%-44.4%). The leaf essential oil was mainly composed 3,5-nonadiyne (35.8%), beta-selinene (20.9%), alpha-funebrene (10.1%) and (Z)-falcarinol (6.1%). The stem oil was dominated by acetylenic compounds (73.8%) represented by 3,5-nonadiyne (67.8%) and (Z)-falcarinol (5.7%). On the contrary, the major components of the flower essential oil were sesquiterpenoids (37.5%), such as germacrene D (16.6%), alpha-funebrene (7.4%), and acetylenic compounds (31.5%), such as (Z)-falcarinol (21.0%) and 3,5-nonadiyne (10.0%). Monoterpenoids constituted 23.9% of the flower oil with limonene (19.9%) as the single major constituent. The essential oil of the roots was dominated by 3,5-nonadiyne (90.5%). The results showed considerable qualitative and quantitative variations in the essential oil compositions of the different plant parts of L. wallichiana. (Z)-Falcarinol (1.9%-21.0%) and alpha-funebrene (0.1%-10.1%) were reported for the first time from the essential oils of L. wallichiana.
采用气相色谱 - 火焰离子化检测器（GC - FID）和气相色谱 - 质谱联用（GC - MS）方法分析了藏新拟川芎（Ligusticopsis wallichiana (DC.) Pimenov & Kljuykov）叶、茎、花和根的精油成分。共鉴定出45种成分，占精油成分的93.2% - 97.8%，其中主要成分是炔类化合物（31.5% - 92.8%）和倍半萜类化合物（0.3% - 44.4%）。叶精油主要由3,5 - 壬二炔（35.8%）、β - 芹子烯（20.9%）、α - 古巴烯（10.1%）和（Z）- 镰叶芹醇（6.1%）组成。茎精油以炔类化合物（73.8%）为主，其中3,5 - 壬二炔（67.8%）和（Z）- 镰叶芹醇（5.7%）为代表。相反，花精油的主要成分是倍半萜类化合物（37.5%），如杜松烯D（16.6%）、α - 古巴烯（7.4%），以及炔类化合物（31.5%），如（Z）- 镰叶芹醇（21.0%）和3,5 - 壬二炔（10.0%）。单萜类化合物占花精油的23.9%，其中柠檬烯（19.9%）为主要成分。根精油以3,5 - 壬二炔（90.5%）为主。结果表明，藏新拟川芎不同植物部位的精油成分在定性和定量上存在显著差异。（Z）- 镰叶芹醇（1.9% - 21.0%）和α - 古巴烯（0.1% - 10.1%）首次从藏新拟川芎精油中报道。
