Add to ORKGA new procedure for determination of alkaloids and other pharmaceutical drugs in urine using thin layer chromatography has been developed. The method utilizes 1 ml of urine in a semiautomated extraction system using Dragendorf reagent and Fast Blue BB for the detection of methylbenzoylecgonine, delta-9-tetrahydrocannabinol, phencyclidine, chlorodiazepoxide and diazepam. A quick, simple, convenient and inexpensive procedure is suitable for qualitative analysis of up to 60 simultaneous samples. It was found to be 100% accurate in detecting authentic samples which were positive by EMIT (enzyme-multiplied immunioassay technique). A study was conducted on samples donated by a local hospital of patients given controlled doses of either Valium, li...
