Abstract:

Thebaine is one of the five major alkaloids of opium. It is a controlled substance (opiate) listed in the US code of Federal Regulations, Title 21 Part 1308,12(1985).Various methods have been developed for its determination, e.g. GC,HPLC, TLC, RIA, CZE, spectrometry, etc. Although potentiometric membrane sensors have been widely used in pharmaceutical analysis, no data has so far been reported for determination of thebaine by potentiometric membrane sensors.
