Abstract

Our investigation deals with extractives which content about 15% of whole biomass. The extracts obtained from poplar bark and foliage, and purified phytochemicals arising from these extracts, can find various applications, e.g., as biopharmaceuti-cals, food additives and nutraceuticals, biopesticides, and cosmetic products. Composition of neutral lipophylic compounds of poplar bark and foliage was studied as far as inflorescences of male and female plants and pollen. Tert-butyl methyl ether (TBME) was used as an extraction solvent for raw materials having all the advantages of diethyl ether, but devoid of its disadvantages. It does not form peroxides and does not create increased gas content due to the higher boiling point. TBME-extracts were investigated by gas chromatography-mass-spectrometry (GC-MS). We found more than 40 lipophilic neutral constituents from raw materials of poplar bark and foliage. 60 lipophilic neutral constituents from raw materials of florescences and pollen including alkanes, sterols, aliphatic and triterpenoic alcohols as far as 34 acidic compounds were identified by GC-MS. The content of inflorescences and pollen extracts differs from bark and foliage constituents.
