SummaryBetween 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, genkvvanin, chrysin, gatangin, 5-hydroxy-4',7-dimethoxyflavone, and pilloin.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
