Scientists from the National Center for Natural Products Research at the University of Mississippi have isolated three compounds from the American beautyberry plant, Callicarpa americana, which have potentials as natural insect repellents. The repellents extracted--callicarpenal, intermedeol and spathulenol-- were found to be effective in repelling mosquitos, particularly those that transmit yellow fever and malaria.

While the compounds could potentially help control mosquito-transmitted diseases, scientists say further research will still have to be performed to ascertain its safety and toxicity levels, and to identify cost-effective production methods.
