Steins Laboratorium, Brørup, Denmark.

A high-performance liquid chromatographic method based on C18 solid-phase extraction and ultraviolet detection at 323 nm of analytes derivatized with benzoic anhydride and 1,2,4-triazole mercuric chloride solution was developed for the simultaneous determination of amoxicillin, penicillin G (benzylpenicillin), ampicillin, oxacillin, cloxacillin and dicloxacillin residues in raw milk. The detection limit of the method was 1.3 microg/l for penicillin G; 1.4 microg/l for amoxicillin, oxacillin and cloxacillin, 1.5 microg/l for ampicillin and 2.7 microg/l for dicloxacillin. The mean recovery was 95-102% for amoxicillin, penicillin G and ampicillin, 92-98% for oxacillin and cloxacillin and 87-94% for dicloxacillin, measured by using an internal standard. The relative repeatability standard deviation was 4-9% on level 4-15 micro/l, respectively, 2-7% on level 30-40 microg/l.

D010400	Penicillin G	A penicillin derivative commonly used in the form of its sodium or potassium salts in the treatment of a variety of infections. It is effective against most gram-positive bacteria and against gram-negative cocci. It has also been used as an experimental convulsant because of its actions on GAMMA-AMINOBUTYRIC ACID mediated synaptic transmission.

D010406	Penicillins	A group of antibiotics that contain 6-aminopenicillanic acid with a side chain attached to the 6-amino group. The penicillin nucleus is the chief structural requirement for biological activity. The side-chain structure determines many of the antibacterial and pharmacological characteristics.
