Age and seasonal variability of essential oil composition in Picea abies L. Karst

Abstract

An essential oil from foliage of Picea abies growing at territories removed from technogenic influence, has been obtained by the hydrodistillation method. The essential oil content in foliage has been determined. The composition of the oil has been studied by gas chromatography, and 19 main components with content 1% w/w or higher, have been identified. It has been established that the yield of essential oil depends on age and sampling time of the green mass. Age and seasonal variability of the oil composition has been studied.
