Summary
Aconitum alkaloids diffuse postmortem in rabbits from the stomach to organs and blood. Urine analysis is key to distinguishing antemortem from postmortem poisoning cases.
Area of Science:
- Forensic Toxicology
- Pharmacokinetics
- Analytical Chemistry
Background:
- Aconitum alkaloids are potent toxins with forensic implications.
- Distinguishing antemortem from postmortem poisoning is crucial in forensic investigations.
- Understanding the distribution of toxins after death is essential for accurate interpretation.
Purpose of the Study:
- To investigate the postmortem diffusion patterns of Aconitum alkaloids and their metabolites in rabbits.
- To establish a reliable method for differentiating antemortem from postmortem Aconitum poisoning.
Main Methods:
- Rabbits were poisoned with Aconitum alkaloids post-sacrifice.
- Biological samples (blood, urine, tissues) were collected at various time points.
- High-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) was used for analysis.
Main Results:
- Aconitum alkaloids and metabolites diffused from the stomach to major organs and blood within 4 hours.
- Spleen, liver, and lung showed higher concentrations, with spleen having the highest.
- Kidney concentrations were low, and alkaloids were not detected in urine.
Conclusions:
- Aconitum alkaloids exhibit postmortem diffusion driven by concentration gradients.
- Urine is unaffected by postmortem diffusion, making it a reliable indicator for poisoning time.
- Findings provide a reference for forensic identification of Aconitum poisoning.
