[The determination of olaquindox in feeds by HPLC].
A liquid chromatographic procedure for the determination of olaquindox in feeds is described. Chromatography was performed on a PC8-10/S2504 (4.0 mm i.d. x 250 mm, 10 microm, Shimadzu Co.) column at 30 degrees C by using a mobile phase of methanol:water (20:80, V/V ) with a flow rate of 0.8 mL/min and UV detection at 260 nm. Acetanilide was used as internal standard. Olaquindox was extracted with dimethylformamide (DMF) from the feeds. The average recoveries of olaquindox were 98.58%-101.63% and the relative standard deviations were 2.67%-4.25%. The method is simple, rapid, reliable and inexpensive.
