Heroin, morphine, and hydromorphone determination in postmortem material by high performance liquid chromatography

Area of Science:

• Forensic Toxicology
• Analytical Chemistry

Background:

• Accurate detection of opioids in postmortem samples is crucial for forensic investigations.
• Existing methods may have limitations in simultaneously identifying heroin and its metabolites.

Purpose of the Study:

• To develop and validate a simultaneous analytical method for heroin, morphine, and hydromorphone in postmortem specimens.
• To establish reliable methods for confirming heroin use in forensic cases.

Main Methods:

• Reversed-phase high-performance liquid chromatography (HPLC) with electrochemical detection was employed.
• Gas chromatography/mass spectrometry (GC/MS) was used for confirmatory analysis.
• Hydrolysis of HPLC fractions was performed to confirm heroin presence.

Main Results:

• The developed HPLC method successfully determined heroin, morphine, and hydromorphone in postmortem tissues.
• Unmetabolized heroin was directly detected in urine samples.
• Morphine and hydromorphone were identified in postmortem blood, gastric contents, urine, and injection site tissues.
• Heroin was exclusively identified in urine samples, not in other tested tissues.

Conclusions:

• The developed HPLC method provides a reliable tool for simultaneous opioid determination in forensic toxicology.
• Direct detection of heroin in urine serves as evidence of drug use.
• The method aids in differentiating opioid presence and metabolism in postmortem investigations.
