Solanine poisoning can cause heart problems, difficulty breathing, and gastrointestinal upset. The aim of this study is to investigate the potential inhibitory effect of It is worth noticing that when the mixture was diluted and tested against the extract of the peel of the potato variety Home Guard, the 10 times diluted peel extract was still active as antifeedant, while the authentic glycoalkaloid mixture was not active at this dilution. The raw potato and skins also contain chaconine, which is toxic and can cause irritation to the digestive tract, nervous system symptoms (tremors), and kidney function disorders. Objective: In humans, cases of minor poisoning cause symptoms such as nausea, stomach-ache, vomiting and diarrhoea, sometimes accompanied by fever. Concentrations of glycoalkaloids normally available while eating potatoes can adversely affect the mammalian intestine and can aggravate IBD. ^ Executive Summary of Chaconine & Solanine ^ Gao SY, Wang QJ, Ji YB (June 2006). Disruption of epithelial barrier integrity is important in the initiation and cause of inflammatory bowel disease (IBD). Potato shoots (eyes), leaves, and stems are higher in glycoalkaloids than potatoes, but green potatoes contain significantly higher amounts of the toxic compounds than non-green portions. doi: 10.2903/j.efsa.2020.6222.
