The two methods were validated in terms of specificity, LODs, LOQs, linearity, accuracy, precision, and matrix effects. They were then applied to a tissue residue depletion study after <jats:italic>G. elegans<\/jats:italic> powder at a dose of 2% per kg feed were fed to pigs.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Compared with precise quantitation, the method validation results indicated that the semi-quantitation method was reliable and acceptable for multicomponent quantification independent of standards. Many <jats:italic>G. elegans<\/jats:italic> alkaloids are widely distributed in most tissues of pigs. Tissue residue depletion studies indicated that 14-hydroxygelsenicine, 11-hydroxygelsenicine, and gelsemoxonine could be used as potential residue markers, and pancreas, small intestine, and lung tissues could be considered as potential residue target tissues of <jats:italic>G. elegans<\/jats:italic>. In addition, both urine and plasma could be used to predict 14-hydroxygelsenicine and gelsemoxonine residues in the liver, pancreas, and small intestinal tissues of pigs.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The developed semi-quantification method can be applied to monitor the application and residue of <jats:italic>G. elegans<\/jats:italic>. The results provide scientific evidence for evaluating the safety of animal-derived food from <jats:italic>G. elegans<\/jats:italic> for consumers and will be helpful for its application and future
