PHILIPPINES — A laboratory study has found that a methanol-based extract of durian fruit triggered cell death in cultured human leukemia cells. The research, published in 2023 in Nutrients, examined Durio zibethinus and adds to scientific interest in natural products.
The finding does not mean eating durian can treat leukemia. Researchers used a specially prepared laboratory extract, not ordinary fruit flesh or juice. The experiment involved one cultured cell line, not patients or animals.
How the Experiment Was Conducted
The study examined HL-60 cells, a human leukemia cell line commonly used in cancer research. Scientists dried and powdered durian material, then used methanol to extract its chemical compounds. The preparation was applied to cultured cells at a measured concentration for 48 hours.
Researchers affiliated with institutions in India, Saudi Arabia, and Portugal conducted the work. The findings appeared in the scientific journal Nutrients in May 2023. The abstract describes an anticancer mechanism observed in the HL-60 cell line.
What Happened Inside Leukemia Cells
Treated cells showed DNA damage and disruption of the normal cell-division cycle. The extract caused cell-cycle arrest in the S phase and G2/M phase. These effects were confirmed through comet and DNA fragmentation assays, according to the published abstract.
The extract also induced apoptosis, a controlled form of programmed cell death. Researchers found higher levels of Bax, caspase-3, and caspase-9, proteins that promote cell death. Levels of Bcl-2 and Bcl-xL, which help protect cells, were reduced.
Why the Findings Are Not a Treatment
The results show biological activity under laboratory conditions, not a proven medical benefit. The experiment did not establish whether the extract can target leukemia cells without harming healthy human cells. It also did not test safety, dosing, or effectiveness in people.
The preparation used methanol, a laboratory solvent, and was not designed for consumption. Eating durian has not been shown to produce the same effects. Patients should not replace prescribed cancer treatments with fruit or homemade extracts.
What Research Must Do Next
Further research is needed to identify the compounds responsible for the observed effects. Scientists must evaluate their safety and determine whether they could have any practical medical application. The study offers a starting point, not a conclusion.
The work adds to broader research on the biological properties of natural products. It shows how a familiar fruit can become a subject of scientific investigation beyond its nutritional value. For now, the evidence remains confined to cells in a laboratory dish.
The study’s abstract describes an intrinsic apoptotic mechanism, but it does not claim that durian is a cancer cure. Readers should treat the finding as early-stage laboratory evidence rather than medical advice.
