Constituents of the essential oil in Solidago canadensis L. from Eurasia.

Abstract

Hydro distilled essential oils in air-dry samples of aerial parts of Solidago canadensis L., (Asteraceae) from eight local invasive populations were investigated by GC-MS analysis. A comparative study on quantity and composition of the essential oils obtained from plants, growing in different ecological and climatic conditions, ontogenesis phase and different plant organs was carried out The major compounds detected in oil samples of S. canadensis were α-pinene (1.3-61.27%), limonene (0.5-22.5%), bornyl acetat (3.4-29.8%) and germacrene D (1.8-39.2%). Samples from inflorescences contained the maximal percentage of monoterpene hydrocarbons, while the leaves' samples showed the maximal cumulative percentage of sesquiterpene and monoterpene hydrocarbons. Data obtained from our studies confirm the availability of alien invasive species Solidago canadensis for medicine and many other purposes. The variability of the qualitative and quantitative composition of essential oils in different geographical locations will allow further selection of form containing the maximum amount of active substances.
