Abstract: The commer-cially available erythromycin was fed to bees by beekeepers.To extract the erythromycin in the honey, the solid phase extraction gave the best results. The most useful method for examination of erythromycin was Thin-Layer Chroma-tography. The limit of test was 5mg/kg. The method could be used to control the quality of honey.

Key words: erythromycin, honey, TLC, solid-phase extraction
