Abstract
ABSTRACT Dynamic headspace (DHS), steam distillation (SD) and simultaneous distillation-solvent extraction (SDE) methods were compared as to recovery and other criteria in the isolation of propolis volatiles. Concentrates of these volatiles were analyzed by GC/MS. High yield, short experimental time, minimal solvent use for routine work, strong representative odor and small concentration factor proved the SDE as the most suitable method.
