Tomatine is a poisonous compound found in all parts of the tomato plant but is largely concentrated in the leaves and stems. Solanine is found in all species of the nightshade family and similarly leaves and stems have high concentrations. Symptoms of alkaloids poisoning include diarrhoea, bloat, and stomach pain.Solanine is a toxic glycoalkaloid known to accumulate under certain conditions in potato plant, sprouts and tuber in levels which, if ingested, may cause poisoning in humans and farm animals.Mechanism of action The toxic mechanism of solanine is caused by the chemical's interaction with mitochondrial membranes. Experiments show that solanine exposure opens the potassium channels of mitochondria, decreasing their membrane potential.
