| Abstract: | Summary Between six and nine flavonoids have been identified by GC-MS in five samples of propolis and in one sample of bud exudate from poplar (Populus nigra), all collected in Poland. On the basis of experimental data and data obtained by use of Drylab software, the optimum temperature programme was found for separation of reference samples of pinostrobin chalcone, pinocembrin, tectochrysin, genkwanin, chrysin, galangin, 5-hydroxy-4′,7-dimethoxyflavone, and pilloin. |
