Paper chromatography and paper ionophoresis of several analgesics related to morphine


, : Paper chromatography and paper ionophoresis of several analgesics related to morphine. Pharmazie 10(8): 470-477

Separation of a series of analgesics of the morphine series were carried out on acid buffered papers with H2O-saturated n-butanol. Thus, Dicodid, codeine, Dilaudid, and morphine may be separated by using differently buffered papers. By paper ionophoresis, compounds with phenolic OH groups may be separated from others by means of 0.1 N NaOH. Racemorphan, Eucodal, Methodan, and other analgesics of the morphine series may be separated. Separation of isomeric compounds with a C=O group can be accomplished by ionophoresis with 1% K2S2O5 solution as electrolyte. Due to the acid nature of the sulfite grouping of the sulfite addition compound, the basic properties of the compound are reversed, the isoelectric point is reached, and only an electro-osmotic transport is now possible. Some members of the morphine group can be differentiated by coupling with diazotized sul-fanilic acid to form various colored compounds. In the separation and isolation procedures, dihydrocodeinone enol acetate is partially split to Dicodid and Heroin partially to monoacetyl morphine. 16 references.
