Syamsul Bahri Siregar text Bogor BBPMSOH 1995 Vol. 4, p. 4-7 id 3 tables; 11 ref. Summary (En) A bioutography procedure was conducted to determine the risedue of salinomycin (SL), monensin (MN) and lasalosid (LS). SL, MN and LS were extracted from chicken meat by homogenizing with acetonitrile and purified by silica cartidge column. The aliquots were spotted on thin layer plate and detected by bioautography. Bacillus subtillis ATCC 6633 was used as test microorganisms. The percentage of averange recoveries of residues from chicken meat found at the level of SL 0.02 ppm, NM 0.05 ppm and LS 0.05 ppm were 73.90 ± 1.00%, 85.65 ± 2.17% and 76.26 ± 2.30%, respectively. A high performance liquid chromatography (HPLC) method with fluoremetric detector was used to determine the residue of LS in chicken meat. The method of extraction was conducted as decribe before. The aliquots were separated by HPLC using an ODS column. The percentage of average recoveries of LS at the level of 0.05 ppm was 75.71 ± 1.20% There was no differences between the percentage of averange recovery of LS at the level of 0.05 ppm wheather using HPLC or LTC Antibiotics -- Residues -- HPLC -- CHICKENS -- SALINOMYCIN -- MONENSIN -- LASALOCID -- THIN LAYER CHROMATOGRAPHY 0852-9612 210323 20210323091301 INLIS000000000000110 Converted from MARCXML to MODS version 3.5 using MARC21slim2MODS3-5.xsl (Revision 1.106 2014/12/19)
