Treatment with bee products in Georgia has been described in popular writings. Among bee products, honey and propolis are of most particular interest. Propolis is characterized by antimicrobial, antiviral, antioxidant, anticarcinogenic and analgesic properties. We have studied relationship between optical density and antimicrobial properties. Almost all samples of Georgian propolis are characterized by high optical density and antimicrobial activity. Studies have discovered that optical density was high in the samples of spring season. The maximal absorption values have been observed at a wavelength of 290-310 nm that is characteristic of flavonoids. Also, the sample with a relatively low optical density （Baghdati district） has exhibited antimicrobial activity that is conditioned not by polyphenols, but flavonoids.展开更多

All of these researches are very important for controlling agricultural insect pests and the diseases they transmit, accelerating the molecular biological research of silkworm, and promoting the international trade of honey bee products. Most of these achievements mentioned above have got the national, provincial, ministerial or municipal awards on science and technology.展开更多
