Central Asia region closes to the biggest opium producing area in the world and then it's drug crime issue is serious especially, so the issue has brought a series of negative effects which cannot be neglected for Central Asia region and neighboring countries' stability and development.
A Novel Poly(methacrylic acid-ethylene glycol dimethacrylate) Monolith Microextraction Coupled with Capillary Zone Electrophoresis Applied to Simultaneous Analysis of Opiates in Human Urine
A review on the determination of opiates in biological samples in recent five years is given, including the structure and properties of opiates, being metabolized in human body, techniques of extraction and cleaning such as LLF, SPE and SFE, and methods of determination such as immunoassay, GC/MS, HPLC and LC/MS.
Emotional evaluation of short musical fragments was compared for healthy people, patients with endogenous or neurotic depression, and opium addicts with affective disorders.
Using gas chromatography, the alkaloids morphine, codeine, thebaine, papaverine and narcotine contained in opium extract have been identified and quanti-fied as free bases in one step without derivation.
For this purpose, accurately weighed amounts of opium extract and internal standard are prepared according to the method described, and an aliquot part of the resultant solution is subjected to gas chromatography under defined conditions.
