A simple, accurate and specific proton nuclear magnetic resonance spectrometric method is described for the quantitative determination of atropine and scopolamine in plants. The method is based on a comparison of the integrated peak areas of the N-CH 3 protons of both compounds (centred at 2.15 and
## Abstract Two half amides of itaconic acid, (**1**) and (**2**), have been synthesized and identified by proton magnetic resonance spectroscopy as a preliminary to an interpretation of the mechanism of action of succinate thiokinase on guanosine triphosphate substrates.
