Variations in the essential oil composition of Thymus serpyllum L., growing wild in Estonia (33 samples) and in some other countries (Russia, Latvia and Armenia, seven samples) were determined. The oil were obtained from Estonia (46 samples) in yields 0.6-4.4 and 1.9-8.2 mL kg(-1) in other countries. The T. serpyllum herb grown in Estonia usually did not confirmed to the EP standard in the aspect of the essential oil contents (3.0 mL kg(-1)). Variations in the essential oil composition of wild thyme were studied using capillary gas chromatographic methods. A total of 94 components were identified. Thymol and carvacrol, mentioned in literature as principial components, are not the main components of the essential oil of wild thyme growing in Estonia. (E)-nerolidol, caryophyllene oxide, myrcene and borneol chemotypes of wild thyme drug are distinguishable. The chemical composition of samples from Russia, Latvia and Armenia is very variable.
对爱沙尼亚野生生长的百里香（33个样本）以及其他一些国家（俄罗斯、拉脱维亚和亚美尼亚，7个样本）的精油成分变化进行了测定。从爱沙尼亚获取的精油产量为0.6 - 4.4 mL kg⁻¹，其他国家为1.9 - 8.2 mL kg⁻¹。爱沙尼亚种植的百里香叶在精油含量方面（3.0 mL kg⁻¹）通常不符合欧洲药典标准。使用毛细管气相色谱法研究了野生百里香精油成分的变化。共鉴定出94种成分。文献中提及的百里香酚和香芹酚并非爱沙尼亚野生百里香精油的主要成分。野生百里香药材的（E）-橙花叔醇、氧化石竹烯、月桂烯和冰片化学型是可区分的。来自俄罗斯、拉脱维亚和亚美尼亚的样本的化学成分变化很大。
