Streptomycin belongs to the group of aminoglycoside antibiotics. It was utilized in apiculture to protect bees against a variety of bee diseases. It was the aim of this study to develop a highly sensitive LC/MS/MS method, which could be validated, for the quantitative determination of streptomycin in honey.
A reliable and sensitive procedure is presented for the analysis of erythromycin (ERY) and oleandomycin (OLE) in food of animal origin, such as meat, liver, kidney, raw milk and egg. The method is based on a solid-phase extraction clean-up with a cation exchange cartridge, a 9-fluoromethylchloroformate (FMOC) precolumn derivatization and a separation by HPLC with fluorometric detection.
Concentrations of polychlorinated biphenyls (PCBs), DDT and its metabolites (DDTs), HCH isomers (HCHs), chlordane compounds (CHLs) and hexachlorobenzene (HCB) were determined in sediment, soil, whole body homogenates of resident and migratory birds and their prey items (including fish, green mussel, snail, earthworm, crabs, prawn, lizard and frogs), bird eggs and bats collected from southern India
A method was developed and validated for determination and quantitation of tilmicosin residues in swine, cattle, and sheep edible tissues, as well as chicken fat, skin, and muscle over a concentration range of 0.025 microg/g-20 microg/g. For chicken kidney and liver, the method was validated over a range of 0.060 microg/g-20 microg/g.
A reliable and sensitive procedure is presented for the analysis of streptomycin (STP) in food of animal origin, like meat, milk and honey. The method is based on a separation by ion-pair liquid chromatography with ?-naphthoquinone-4-sulfonate (NQS) postderivatization and fluorescence detection.
A validated, highly sensitive and precise high-performance liquid chromatographic (HPLC) method for the determination of the macrolides erythromycin, azithromycin, clarithromycin and roxithromycin in human serum is described.
Persistent organochlorines such as DDT and its metabolites (DDTs), hexachlorocyclohexane isomers (HCHs), chlordane compounds (CHLs), hexachlorobenzene (HCB), and polychlorinated biphenyls (PCBs) were determined in whole-body homogenates of resident and migratory birds collected from South India. Organochlorine contamination pattern in birds varied depending on their migratory behaviour.
