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 2.5 ppm) with that of the sharp singlet of 1, 4‐dioxane (positioned at 3.5 ppm) which is used as the internal standard. © 1998 John Wiley & Sons, Ltd.
