Вариабельность основных компонентов эфирного масла пихты одноцветной ( Abies concolor), произрастающей в условиях урбанизированной среды

The chemical composition of essential oil from A. Concolor growing in urban environment has been studied, 48 ingredients being identified and their content measured. The results obtained demonstrate the relationship between certain ingredients’ content and envuironment pollution by toxic elements, that can be used as an indicator of the environment condition.Исследования позволили детально рассмотреть химический состав эфирного масла пихты A. Concolor , произрастающей в условиях урбанизированной среды, идентифицировать и количественно измерить содержание 48 компонентов. Представленные результаты наглядно демонстрируют зависимость содержания отдельных компонентов в масле от степени загрязненности территории произрастания токсичными элементами и могут использоваться в качестве индикатора состояния окружающей среды

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

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 in the 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 calculate standard 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
