Title: High Performance Capillary Electrophoretic Determination of Residual Amounts of Penicillin Drugs in Chicken
Abstract:Chicken samples were pretreated by the following 4 methods separately: ① NaH2PO4-extraction(SE),② NaH2PO4-solid phase extraction(SE-SPE),③ matrix solid-phase dispersion extraction(MSPDE)and ④ matrix s...Chicken samples were pretreated by the following 4 methods separately: ① NaH2PO4-extraction(SE),② NaH2PO4-solid phase extraction(SE-SPE),③ matrix solid-phase dispersion extraction(MSPDE)and ④ matrix solid-phase dispersion extraction-SPE(MSPDE-SPE).The contents of penicillin,ampicillin and amoxicillin in the sample solutions were determined by high performance capillary electrophoresis(HPCE).As shown by the results obtained by recovery tests and chromatographic separation,the pretreatment method ② was more suitable to be used for simultaneous determination of the 3 penicillin drugs.Tests for recovery and precision of the proposed method were tested,values of recovery and RSD′s(n=5) found were in the ranges of 73.1%-95.9% and 2.9%-9.8% respectively.Read More
