Dichloromethane. Hydrochloric acid, 2 N. Furaxolidone standard, 100 pg ml-l in water-
satwated dichloromethane. The furazolidone standard solution used for quantitation during …

A method is presented for the detection of the nitrofuran antibacterial, furazolidone in animal
feeds. Following solvent extraction of feed samples, the extracts were purified on an alumina …

Furazolidone is separated from finished feeds by acetone-water extraction on a Goldfisch
apparatus. Extracting solvent is removed, and the residue is dissolved in dimethylformamide …

A liquid chromatographic (LC) method for determining furazolidone in finished feeds and
premixes was collaboratively studied. Finished feed sample is extracted with acetone-water …

Furazolidone is used as a therapeutic antibacterial agent in swine, cattle, and poultry and is
also used as a growth promotant in swine. In the latter use the drug is added to feeds in …

A sensitive HPLC method for the determination of furazolidone residues in eggs (10-1,000
micrograms/kg) is described. Recovery is about 86%. With the aid of a UV/Vis Diode-Array …

MATERIALS AND METHODS Instrumentation. High-performance liquid chroma-tography
was carried out on a Perkin-Elmer system con-sisting of a Series 3 modular chromatograph …

Urine and plasma were applied directly to the Extrelut 1 columns. Tissues were ground and
extracted before chromatography. Because of the effective clean-up method, isocratic high …

MATERIALS AND METHODS Chemicals and Supplies. Furazolidone was obtained from
Sigma. Acetonitrile was HPLC grade (Baker). Water was puri-fied by the Milli-Q four-bowl …

The feed sample is extracted with acetone or dimethylformamide-acetone (1+ 1) and the
filtered extracts are evaporated to dryness. The residue is dissolved in chloroform and …
