The essential oil needles of Thuja occidentalis L. and Tetraclinis articulate (Vahl) Masters (synonym: Thuja articulate) growing in Canada, were analyzed by HS-SPME / GC-MS technique. Thirty one and fifty one compounds were identified representing 92.30% and 93.42% of the oil, respectively. The main constituents of Thuja occidentalis were bornylacetate (30.00%), limonene (7.56%), camphor (7.33%), α-pinene (7.18%) and δ-cadinene (6.01%), whereas α-pinene (32.67%), 3-carene (18.29%), β-myrcene (11.69%) and bornylacetate (5.88%) were the major constituents of Tetraclinis articulata. The results showed that T. occidentalis chemotype was bornylacetate whereas α-pinene was chemotype of Tetraclinis articulate and HS-SPME method can be applied to routine control analysis of aromatic and medicinal plants

Kanada’da yetişen Thuja occidentalis L. ve Tetraclinis articulate (Vahl) Masters (synonym: Thuja articulate) türlerinin ibrelerinden elde edilen yağlar HS-SPME / GC-MS tekniği ile analiz  edildi. Sırasıyla %92.30 and %93.42’lik toplam yağ miktarında otuzbir ve ellibir bileşen tespit edildi. Thuja occidentalis’in ana bileşenleri bornilasetat (%30.00), limonen (%7.56), kamfor (%7.33), α-pinen (%7.18) ve δ-kadinen (%6.01) olarak belirlendi; Tetraclinis articulata’da ise α pinen (%32.67), 3-karen (%18.29), β-mirsen (%11.69) ve bornilasetat (%5.88) ana bileşenler olarak bulundu. Sonuçlara gore T. occidentalis’in kemotipi bornilasetat, T. articulata’ nın kemotipi α-pinen olarak belirlenmiş ve HS-SPME yöntemi tıbbi ve aromatik bitkilerin rutin kontrol ve analizlerinde kullanılabilecek bir yöntem olarak belirlenmiştir.
