Collaborative study of assay method for erythromycin in pelleted feeds containing binding agents. 1977

V W Winkler, and M A Nyman

A modified method for analysis of erythromycin in feeds containing the pelleting adjuvants bentonite and Masonex has been evaluated by collaborative study. Erythromycin is freed from the binding action of these adjuvants by an aqueous methanolic pH 8 buffer presoak before extraction with methylal. The recovery values for mash and pellets of 6 different sample types range from 86.6 to 103.0% of theory with a grand mean of 96.8%. This modification has been adopted as official first action.

D011134 Polysaccharides Long chain polymeric CARBOHYDRATES composed of MONOSACCHARIDES linked by glycosidic bonds. Glycan,Glycans,Polysaccharide
D002021 Buffers A chemical system that functions to control the levels of specific ions in solution. When the level of hydrogen ion in solution is controlled the system is called a pH buffer. Buffer
D004917 Erythromycin A bacteriostatic antibiotic macrolide produced by Streptomyces erythreus. Erythromycin A is considered its major active component. In sensitive organisms, it inhibits protein synthesis by binding to 50S ribosomal subunits. This binding process inhibits peptidyl transferase activity and interferes with translocation of amino acids during translation and assembly of proteins.
