Rationale: Gelsemium elegans (G. elegans) is highly toxic to humans and rats but has insecticidal and growth-promoting effects on pigs and goats. However, the mechanisms behind the toxicity differences of G. elegans are unclear. Gelsenicine, isolated from G. elegans, has been reported to be a toxic alkaloid. Methods: In this study, the in vitro metabolism of gelsenicine was investigated and compared for the first time using human (HLM), pig (PLM), goat (GLM) and rat (RLM) liver microsomes and high-performance liquid chromatography/mass spectrom...
