Abstract: | We have used 1H and 13C NMR spectroscopy to analyze the chemical composition of essential oil from needles of Canadian spruce (Picea glauca (Moench) Voss) grown in different regions of the Republic of Belarus. We consider the change in the composition of the oil depending on the area where the spruce was grown. We suggest using spruce needle essential oil as a biological indicator for environmental conditions in the area. |
