A rapid and sensitive method for extracting temazepam from human serum and urine is presented. Free temazepam is extracted from plasma and urine samples using n-butyl chloride with nitrazepam as the internal standard. Temazepam glucuronide is analyzed as free temazepam
Commentary on: Dou C, Bournique J, Zinda M, Gnezda M, Nally A, Salamone S. Comparison of rates of hydrolysis of lorazepam-glucuronide, oxazepam-glucuronide and temazepam-glucuronide catalyzed by E. coli beta-glucuronidase using the on-line benzodiazepine screening immunoassay on the Roche/Hitachi 917 analyzer.

Protocols

Using UHPLC/MS (TOF) for Detection of Drugs and Metabolites in Urine Following Optimized Enzymatic Hydrolysis Conditions

To optimize hydrolysis using β-glucuronidase, factors such as incubation time, temperature, hydrolysis pH, enzyme source, and enzyme concentration must be evaluated for each glucuronide metabolite to be analyzed.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
