title: Biological properties and clinical application of propolis. I. Some physico-chemical properties of propolis.
abstract: The presence of 19 elements has been shown in the ethanol extracts of propolis (EEP). Three fractions have been obtained by filtration through a structural gel that did not show an initial antibacterial activity when investigated separately. Fractions 2 and 3 joined together have regained this activity. EEP solutions maintain their anitbacterial activity in acidic or neutral pH. Insensitivity of EEP solutions on temperautre of 75 degrees C for 30 min has been found.
