| Abstract: | The chemical composition of essential oil samples from needles of six species of five-needle pines (Pinus pumila, Pinus sibirica, Pinus parviflora, Pinus armandii, Pinus koraiensis, and Pinus cembra) and one natural interspecific hybrid Pinus sibirica × Pinus pumila has been studied by the chromato-mass spectrometry method. Essential oils have been prepared by simultaneous steam distillation-extraction. The analysis of the samples?? composition showed that the main constituents of the essential oils were the following mono- and sesquiterpenic compounds: ??-pinene (5?C63%), camphene (0.7?C3.6%), ??-pinene (0.7?C7%), ??-myrcene (0.5?C3.4%), 3-carene (0?C16%), limonene (0.6?C7.9%), ??-phellandrene (0.7?C5.3%), terpinolene (0.4?C6.7%), bornyl acetate (0.2?C12%), ??-terpenyl acetate (0?C4.6%), caryophyllene (0.4?C24%), humulene (0.1?C4%), germacrene D (0.1?C24%), bicyclogermacrene (0.1?C3.6%), ??-cadinene (0.9?C2.3%), ??-cadinene (2.2?C6.1%), germacrene D-4-ol (0?C6.8%), T-cadinol (0.7?C2.9%), and ??-cadinol (0.7?C6.0%). |
