Abstract : Canadian goldenrod (Solidago canadensis L.) is a perennial herb introduced from North America and widely distributed in most European countries, often regarded as an invasive plant threatening the native species, simultaneously being a hard-to-control weed in agriculture. Nevertheless, due to its application in traditional herbal medicine (as Solidaginis herba), S. canadensis also constitutes a cheap and readily available medicinal raw material. The content of such metabolites as flavonoids, polysaccharides, diterpenes and triterpenoid saponins in this plant is well characterized, whereas the data on the occurrence of triterpenoids and steroids in a free (not conjugated) form are scarce. Thus, the present study was aimed toward the gas chromatography-mass spectrometry (GC-MS) analysis of the extracts obtained from inflorescences (branched panicles) and leaves of S. canadensis. Diethyl ether extracts were obtained from dried and powdered samples of S. canadensis leaves and inflorescences divided into flowers and stems. Analysis was made by gas chromatography-mass spectrometry method (GC-MS). In both inflorescences and leaves, the significant contents of triterpenoids belonging to lupane-, oleanane- and ursane- groups were found, i.e., lupeol acetate, β-amyrin, and α-amyrin accompanied by its ketone, α-amyrenone. Flowers were the richest source of triterpenoids (approx. 1.2 mg/g of dry weight), whereas the contents in leaves (0.91 mg/g d.w.) and inflorescence stems (0.69 mg/g d.w.) were lower. In all analyzed extracts one compound belonging to plant Δ7-sterols, spinasterol, was found, present mainly as an ester conjugate.
