Abstract - Phenolic composition of Bulgarian and Mongolian propolis and their possible plant sources (the resinous secretions of different tree buds) were investigated by gas chromatography-mass spectrometry (GC/MS). The results obtained demonstrate that in both countries propolis is collected mainly from poplars: from Populus nigra and to some extent from P italica in Bulgaria, and from P suaveolens in Mongolia.
Key words: propolis / poplar bud / phenolics / GC/MS / Populus
