 Title    Trace Elements in Propolis and in its Ethanolic Extract (E E P ) as Determined by Neutron Activation Analysis  
 Abstract    Propolis is a natural composite balsam, manufactured by honey bees, and active biochemically. Some of its biologi­ cal effects are attributed to its ability to stimulate enzymatic systems, which in many instances involve trace elements. In the present study we assayed propolis and its ethanolic ex­ tract (EEP) for trace elements, and quantified them with the aid of neutron activation analysis. Four elements that have been detected in propolis and EEP for the first time are Na. Cr, Co (ppm) and Ag (ppb). The wide concentra­ tion range of the inorganic components in various batches of propolis and EEP is due to the difference in their extrac­ tion capacities, and to the variability in the environmental pollutants and the flora at the beehive sites.
