چکیده

A simple and sensitive method for the determination of cynarin is described and partially validated. The assay was used to determine the pharmacokinetic profile of cynarin after Wistar rat intravenous administration. Cynarin was isolated from rat plasma by solid-phase extraction. Separations were performed by reversed-phase high-performance liquid chromatography with ultraviolet detection. RESUMEN. “Validación de un Método para la Valoración por HPLC de Cinarina en Muestras Biológicas”. En el presente trabajo se describe y valida parcialmente un método simple y con una adecuada sensiblilidad para la determinación de cinarina en plasma. Este método fue utilizado para determinar el perfil farmacocinético de la cinarina luego de la administración endovenosa a ratas wistar. La cinarina fue aislada del plasma de rata por extracción en fase sólida. Las muestras obtenidas se analizaron por HPLC en fase reversa con detección ultravioleta.

Simultaneous Chloramphenicol and Florfenicol Determination by A Validated DLLME-HPLC-UV Method in Pasteurized Milk

The antibiotic residues in milk are a well-known serious problem and pose several health hazards to consumers. We have described a simple, rapid, and inexpensive DLLME-HPLC/UV technique for the extraction of chloramphenicol and florfenicol residues in milk samples. Under the optimum conditions, linearity of the method was observed over the range 0.02-0.85 µg/L with correlation coefficients > 0....
