Propolis is a sticky, resinous substance made by honeybees and used in their hives as an all-purpose sealer. Because propolis is made from sap, pollen and other collected indigenous compounds, it shows geographic variance. Previous studies have shown that some chemicals contained within propolis have a wide variety of biological activity. Samples of propolis gathered from Western Pennsylvania were prepared for analysis by flash freezing and grinding to a powder. The natural products were extracted from the raw propolis using a number of different techniques. Characterization was conducted primarily through GC-MS revealing over sixty different chemicals, not including waxes, in the propolis samples. Synthetic efforts have also been taken towards the preparation of some chalcones and flavonoids identified in the samples. All isolation, characterization and syntheses will be described.
