Chemical diversity of the essential oils of twenty wild populations of Tanacetum polycephalum Sch. Bip., was investigated. The aerial parts of T. polycephalum were collected at full flowering stage from West Azerbaijan Province of Iran, air-dried; hydrodistilled to produce essential oils. The essential oils were analyzed by GC-FID and GC-MS. A total of forty compounds were identified accounting for 96.4-99.9% of the total oils. The most principal compounds were cis-thujone (0-82.3%), trans-thujone (0-79.8%), camphor (1.3-75.0%), 1,8-cineole (4.5-43.3%), borneol (1.0-36.2%) and bornyl acetate (0-26.8%). Hierarchical cluster analysis based on the percentages (>0.5%) of the essential oils components was carried out to determine the chemical diversity among the populations studied. The cluster analysis resulted in the identification of four main chemotypes namely: 'camphor + 1,8-cineole', 'mixed', 'cis-thujone' and 'trans-thujone'.
对20个多头菊蒿（Tanacetum polycephalum Sch. Bip.）野生种群的精油化学多样性进行了研究。在伊朗西阿塞拜疆省多头菊蒿盛花期采集地上部分，风干后进行水蒸馏以制备精油。精油通过气相色谱 - 火焰离子化检测器（GC - FID）和气相色谱 - 质谱联用仪（GC - MS）进行分析。共鉴定出40种化合物，占总油含量的96.4 - 99.9%。最主要的化合物为顺式侧柏酮（0 - 82.3%）、反式侧柏酮（0 - 79.8%）、樟脑（1.3 - 75.0%）、1,8 - 桉叶素（4.5 - 43.3%）、冰片（1.0 - 36.2%）和乙酸龙脑酯（0 - 26.8%）。基于精油成分百分比（>0.5%）进行层次聚类分析，以确定所研究种群之间的化学多样性。聚类分析结果确定了四种主要化学型，即：“樟脑 + 1,8 - 桉叶素”型、“混合”型、“顺式侧柏酮”型和“反式侧柏酮”型。
