 Title    Propolis from Chilean Matorral Hives  
 Abstract    Viscidone (0.5%), vanillin, 3',4'-(m ethylendioxy)acetophenone, 3-ethoxy-4-methoxybenz-aldehyde, cinnamic acid, 3-methoxy-4-hydroxymethyl ester were isolated from propolis o f hives from Cuncumen. This is the first report on propolis composition o f an arid and a Mediterranean type climate area.

 Title    Identification of Amino Acids in Brazilian Propolis  
 Abstract    A m ino acids o f propolis samples from different origins were analysed and quantified. Seven of them presented almost the same percentage in all samples, indicating that bees may have obtained amino acids from three sources: plants, pollen contamination and from their own metabolism. The regeneration properties of propolis in relation to the presence of som e amino acids are discussed.

 Title    Feral Honey Bees in the Sonoran Desert: Propolis Sources other than Poplars (Populus spp.)  
 Abstract    In Central Europe and other temperate regions the lipophilic bee hive product propolis normally originates from the bud exudate of poplar trees that is collected by the bees. Based on bee observations, various other sources have been discussed in particular for tropical regions, but in only few cases the origin has been proved by analytical methods. We have analyzed propolis samples from managed honey-bees as well as from feral bee colonies in the Sonoran Desert. Propolis collected in hives out of flight reach of poplars contained flavonoid aglycones and other phenolics that point to specific plants as the source of propolis in this area, namely Ambrosia deltoidea and Encelia farinosa.
