The volatile constituents of the rare species of Hypericum, namely Hypericum pruinatum (as one population) and Hypericum aviculariifolium subp. depilatum var. depilatum (endemic, as two populations namely 'Gümüş' and 'Yeniköy') growing wild in the mountainous parts of Northern Turkey were studied for the first time. The essential oils (EOs) were extracted by hydrodistillation of the air-dried aerial parts and analysed by GC-FID and GC-MS. A total of 56, 49 and 50 EO components representing 98.2%, 96.9% and 99.4% of the total composition were identified respectively from one population for H. pruinatum and two populations for Hypericum aviculariifolium subp. depilatum var. depilatum. GC-MS profiles showed significant compositional variations not only between the two Turkish species, but also between the two populations of the same species highlighting the importance of genetic factors affecting secondary metabolite profile.
首次对生长在土耳其北部山区的珍稀物种贯叶金丝桃（作为一个种群）和金丝桃矮化亚种去毛变种（特有种，分为两个种群，即“Gümüş”和“Yeniköy”）的挥发性成分进行了研究。通过对风干的地上部分进行水蒸馏提取精油，并通过 GC-FID 和 GC-MS 进行分析。从贯叶金丝桃的一个种群中分别鉴定出 56、49 和 50 种精油成分，分别代表总成分的 98.2%、96.9%和 99.4%；从金丝桃矮化亚种去毛变种的两个种群中分别鉴定出 56、49 和 50 种精油成分，分别代表总成分的 98.2%、96.9%和 99.4%。GC-MS 图谱不仅显示了这两个土耳其物种之间存在显著的组成差异，而且还显示了同一物种的两个种群之间存在显著的组成差异，突出了遗传因素对次生代谢产物谱的影响。
