NMR analysis of the composition of essential oil of fur during its evaporation

Comparative analysis of the composition of essential oil of fir during its evaporation in air for 12 weeks by method of NMR 1 H and 13 C was carried out. 12 major essential oil components were identified and quantified. It was found that the compositional change of essential oil is reflected experimentally in the quantitative content of components, and caused mainly by evaporation of highly volatile compounds. The oxidation and polymerization processes in new products approve themselves slightly
