title: Chemical Composition of the Essential Oil of the Boreal Relict of Pyrola rotundifolia L. from Northern Kazakhstan.
abstract: In Kazakhstan Pyrola rotundifolia L. is the plant-relict in the flora of insular pine forests of the region of low hillocks and declivities in Kazakhstan - a group of insular pine forests of Kokshetau, Bayanaul and Karkaralinsk. In this study, the essential oils from dried aerial parts of P. rotundifolia, collected in natural habitats of the State National Natural Park "Burabay" (Akmola oblast, Northern Kazakhstan), were extracted by hydrodistillation and analyzed by gas chromatography - mass spectrometry. The yield of the essential oil amounted to 0.057 % in relation to the mass of the air-dry raw material. The major components in dried plant oil were 2,6-dimethyl-1,4-naphthoquinone (12.99-93.49%) and dibutyl phthalate (4.42-40.48%), depending on the growth conditions.
