Abstract
The authors obtained a phenol hydrophilic propolis agent soluble in water and hardly soluble in 95% ethyl alcohol, practically insoluble in ether, chlorophorm, acetone, and other organic solvents. Some of its technological properties were evaluated: moisture absorption, volume density, friability, extrusion power. The composition of phenol compounds in the agent was analyzed by means of one- and two-dimensional chromatography. The complete UV-spectrum of the agent in comparison with raw material propolis was evaluated. The highest optical density was observed at the wave-legnth from 220 to 390 nm. The absorption maximum was at the range of 290 nm.
