      Planta Med. 84(12-13), 935-940 (2018). Atropine sulfate was hydrolyzed into tropine in a bath of barium hydroxide 8% (temperature 75°C, time 16h). For verification, an aliquot of the final solution was extracted into dichloromethane, which was applied, as well as alkaloid standards, on TLC silica gel and eluted with dichloromethane – ethanol – triethylamine 46:46:1. The reaction was confirmed as complete.
