Abstract
|
|
|
|
Solid phase extraction(SPE) and matrix solid phase dispersion(MSPD) have been studied as preparation procedures for tetracyclines analysis by high-performance liquid chromatography(HPLC) in meat. The recovery range was 7498% for SPE, and 7293% for MSPD at spiked levels of 100ng/g for oxytetracycline(OTC), tetracycline(TC), chlortetracycline(CTC), and doxycycline(DC). The detection limits were 1578ng/g for SPE and 2584ng/g for MSPD, respectively. Analytical method was HPLC with UV detector. The purpose of this study was developing a practical, accurate and precise method for rapid extraction and quantitation of tetracycline residues in meat.
