“…Those potatoes processed at a later timepoint had the highest levels of GA, which suggest that the conditions at which the potatoes are stored induce the level of GA in the potatoes. This confirms a previous result showing that prolonged storage under either indirect sunlight, dark room, dark room with cooling, or under fluorescent light were all associated with increased levels of GA in potatoes [8]. The concentration of solanidine increased as well during the storage of the potatoes.…”

“…The concentrations of GAs is highest in the blossoms (3000-5000 mg/kg) compared to the sprouts (2000-4000 mg/kg) and peel (300-600 mg/kg), whereas the average level across the entire potato tubers is approximately 100 mg/kg [7]. Furthermore, the level of GAs increases during the storage of potatoes after harvest [8].…”

“…), normal metabolic pathways change in potato, which lead to the synthesis of abnormal amounts of numerous novel compounds and secondary metabolites, including toxic glycoalkaloids (GA), at levels that exceed the amount found in healthy tissues, also accompanied by the synthesis of other not usually found in the absence of stress [38]. An important role in the natural disease resistance of tubers is played by GA (in particular, steroid glycosides α-Solanine, and α-Chaconine), being concentrated mainly in their integumentary tissues [37]. However, GA is also potentially health-threatening toxic compounds in potatoes that pose a serious potential hazard to humans [38,39].…”

“…Under unfavorable storage conditions (i.e. pathogen attack), normal metabolic pathways change in potato, which leads to the synthesis of abnormal amounts of numerous novel compounds and secondary metabolites, including glycoalkaloids (GA) (α-Solanine and α-Chaconine are 95% of the total GA), which is believed are associated with antimicrobial, antifungal activities [35,36], and play an important role in the disease resistance of tubers [37]. With that, elevated GA levels in potatoes (200 mg/kg of tubers are considered as critical) are toxic compounds that pose a serious potential hazard to humans [38,39].…”

“…antioxidant activities (Uchida et al 2017;Mahieddine et al 2018;Fratianni et al 2020) and steroidal alkaloids widely reported for its toxic effects. The surge in concentration levels of steroidal alkaloids (glycoalkaloids) is triggered by the exposure of Solanum plants to the sun's UV light or because of mechanical injury including peeling and slicing (Dao and Friedman 1994;Kasnak and Artik 2018. Some of the toxic effects of glycoalkaloids are due to anticholinesterase effects on the central nervous system (Caprioli et al 2014;Lelario et al 2019) and disruption of cell membranes (Blankemeyer et al 1998;Nepal and Stine 2019.…”
