Chemiluminescence behavior of the reaction of potassium permangabate inployphosphoric acid medium with a series of alkaloids. includinng morphine, codeine wasstudied . A novel method for determination of these alkaloids in urine of `drug addicts and in opium was established using reversed phase high performance liquid chromatography withchemiluminescence detection The detection limit for morphine is 1. 0 × 1013 g/L,.
A rapid method for the simultaneous determination of condeine,morphine,thebaine,papaverine and narcotine in opium by gas chromatography with widebore capillary column is described.
There were three main techniques of extraction and cleaning , such as liquid-liquid extraction(LLE), solid phase extraction(SPE) and supercritical fluid extraction(SFE).
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.
