Project of method developing of quality control of spruce essential oil by gas-liquid chromatography

摘要

Conditions of the chromatography analyses of essential oils providing the yield of all components with the contents over 0.01% were selected. Essential oils of 10 samples of Norway spruce growing inthe same edaphic-climatic conditions of the park UE “Brovki” were obtained by hydrodistillation. Qualitative and quantitative analyses of the received essential oils were performed. More than 50 components composing the essential oil were identified. The obtained statistic data allowed to calculatestandard deviation of repeatability, standard deviation of intermediate precision with a variable factor “time + operator”, expanded uncertainty of measurement results for the confidence level P = 0,95.
