"In laboratory experiments, commercially-available grapeseed extract forced the cancer cells to "commit suicide", found the researchers.
Within 24 hours, 76 per cent of leukaemia cells exposed to the extract died through a process of natural self-destruction called apoptosis. Healthy cells remained unharmed.
The researchers believe the discovery could open the door to promising new treatments for the disease which affects more than 24,000 adults and children a year.
But they warn it is too early to justify recommending that people eat grapes or take grapeseed extract in an attempt to stave off cancer.
Grape seeds contain a number of antioxidant plant chemicals including resveratrol, which is known to have anti-cancer properties.
Previous research has shown that grapeseed extract has an effect on skin, breast, bowel, lung, stomach and prostate cancer cells in the laboratory."
