The Scent of Decomposition: What a Rare Flower Reveals About Human Remains
Forensic scientists have long studied the chemical composition of decomposing human remains to aid in crime scene investigations. Now, researchers are looking at an unlikely source to better understand these processes… the corpse flower.
What Is the Corpse Flower?
The Titan Arum (Amorphophallus titanum), also known as the corpse flower, is famous for its overpowering stench, which resembles rotting flesh. This rare plant emits its foul odour to attract insects that feed on decaying organic matter, mimicking the scent of decomposition.
A New Approach to Detecting Human Remains
Bridget Thurn, a forensic scientist at the University of Technology Sydney, has been studying the volatile organic compounds (VOCs) released by the corpse flower to compare them with those found in decomposing human bodies.
Key compounds in both include:
– Cadaverine and putrescine – Responsible for the foul, rotting smell.
– Sulphur-based compounds – Common in both decomposing flesh and the odour of the corpse flower.
– Fatty acid derivatives – Found in both human remains and plant emissions.
How This Research Helps Forensic Investigations
Understanding the chemical markers of decomposition has practical applications for forensic teams, particularly in search and rescue missions. By refining scent-detection techniques, scientists hope to improve the effectiveness of cadaver dogs and forensic technologies used to locate human remains.
This research could also lead to new tools for mass disaster response, where detecting bodies buried under rubble or hidden in natural environments is critical.
