Determination of Some Penicillin Derivativies Using High Performance Liquid Chromatography

Abstract

A rapid, precise and selective method is described for determination of penicillin derivatives. Penicillin derivatives are separated from closely related degradation products by high performance liquid chromatography at ambient temperature using 10cm column packed with 5um Nucleosil RP₁₈ and buffered aqueous acetonitrile as mobile phase. The eluate is monitored at 254nm. The procedure is suitable for determination of 8 penicillin derivatives either in raw material or phamaceutical dosage forms.
