Effect of tea making and boiling processes on the degradation of tropane alkaloids in tea and pasta samples contaminated with Solanaceae seeds and coca leaf. Food chemistry, 2019, Jul-30, Volume: 287 In this study, the degradation of tropane alkaloids in pasta under boiling (100 °C during 10 min) and tea making (100 °C and let cool 5 min) conditions has been evaluated for the first time. Pasta and green tea were contaminated with Datura Stramonium and Brugmansia Arborea seeds (pasta and green tea), whereas coca leaf tea was directly analysed. The compounds were extracted using solid-liquid extraction coupled to a preconcentration stage (only for the cooking water), and the compounds were analysed by liquid chromatography coupled to mass spectrometry (Exactive-Orbitrap analyser). Degradation studies indicate that concentration of tropane alkaloids decreases, and it depends on the compound, observing the highest degradation for tropinone, tropane, cuscohygrine and tropine, as well as it was observed that compounds migrated to the aqueous phase during cooking step. Finally, post-targeted analysis was performed and other tropane alkaloids were found, as scopine, tigloidine or convolvine, showing a similar behaviour under cooking conditions.

Toxicity of field bindweed (Convolvulus arvensis) to mice. Veterinary and human toxicology, 1995, Volume: 37, Issue:5 The effects of feeding high and low doses of field bindweed (Convolvulus arvensis) to mice were investigated. Bindweed contains several alkaloids, including pseudotropine, and lesser amounts of tropine, tropinone, and meso-cuscohygrine. Mice fed bindweed exclusively died or were euthanized after 4-7 d and had severe hepatic necrosis and gastritis with ulceration or erosions. Mice fed low doses of bindweed along with standard laboratory mouse diet for 6 or 8 w had no clinical disease or gross lesions on necropsy examination but did have histologic lesions of mild multifocal hepatitis and gastritis.
