Abstract
Oxytetracycline (OTC) in royal jelly can be extracted by organic solvents and Amberlite XAD-2 resine column chromotography, and the average of OTC recovery was 64.86±6.14%. The cylinder-plate method is generally used for the assay of OTC residue with Bacillus cereus var. mycoides (ATCC 11778). Different dosages of OTC were applied to honeybee colonies to control foulbrood. The dissipation curves of OTC residue were achieved by periodically detecting samples of royal jelly. The curve showed that the OTC residue reduced to about 10% of initial residual level within 13 days (4 samplings). After then, the OTC residue dissipated slowly to undetectable level. For hives received 200 ppm (0.125 g) OTC twice, 100 ppm (0.063 g) twice and 50 ppm (0.031 g) once, the periods needed for residual dissiption to lower than 0.05 ppm were 45, 35 and 24 days, respectively.
