Abstract
Six great ape species (chimpanzees, bonobos, Western gorillas, Eastern gorillas, Sumatran orangutans and Bornean orangutans) live in tropical forests of Africa and South-East Asia. Their habitat, severely threatened by deforestation, contains a vast chemical and biological diversity. During the last decade, we have isolated and identified novel pharmacologically active compounds from plants used by wild chimpanzees in Kibale National Park, Uganda. Our continuous observations over the last 12 years confirm that chimpanzees, when sick, may ingest plant material that are not generally eaten, supporting the existence of self-medication among great apes. Knowledge of great-ape diseases, and the medicinal resources of tropical forests, may be improved by preserving and studying our closest relatives in their natural habitat.
