GLC/TLC analysis of codeine and morphine in urine via derivatization techniques. 1980

D F Mathis, and R D Budd

A procedure has been developed for the TLC and GLC analysis of codeine and morphine derivatives in urine in cases where there is too much interference for TLC analysis as free drugs. Urine is hydrolyzed, then split into two fractions. One fraction is extracted with a polar solvent, concentrated, and acetylated. An aliquot is injected in a 3% OV-17 column and the rest is spotted on a plate developed in hexane:chloroform:diethylamine (50:30:6). The other fraction is ethylated (converting morphine to ethylmorphine), extracted with a nonpolar solvent, concentrated, acetylated, concentrated, and then spotted on a plate developed in hexane:n-butanol:acetonitrile:diethylamine (80:5:5:10). Codeine and morphine can be detected without interference at concentrations as low as 0.3 micrograms/mL.

D009020	Morphine	The principal alkaloid in opium and the prototype opiate analgesic and narcotic. Morphine has widespread effects in the central nervous system and on smooth muscle.

D009022	Morphine Derivatives	Analogs or derivatives of morphine.	Morphines
D002849	Chromatography, Gas	Fractionation of a vaporized sample as a consequence of partition between a mobile gaseous phase and a stationary phase held in a column. Two types are gas-solid chromatography, where the fixed phase is a solid, and gas-liquid, in which the stationary phase is a nonvolatile liquid supported on an inert solid matrix.

D002855	Chromatography, Thin Layer	Chromatography on thin layers of adsorbents rather than in columns. The adsorbent can be alumina, silica gel, silicates, charcoals, or cellulose.

D003061	Codeine	An opioid analgesic related to MORPHINE but with less potent analgesic properties and mild sedative effects. It also acts centrally to suppress cough.
