The fungi belonging to the genus Ganoderma have been used since ancient times / in Eastern traditional medicine in the treatment and prevention of several diseases such as o cancer, hypertension and diabetes, among many other conditions. More than 140 c i x biologically active triterpenoids and 200 polysaccharides, as well as proteins and é M n miscellaneous metabolites have been isolated from the fruiting bodies, mycelium and spores e a of different species of Ganoderma. The aim of this study is to summarize the main biologically s e r active metabolites isolated from members of this genus to date, yet without pretending to be p m I . an exhaustive review, since that would be impossible due the dynamism of the field. a í g o Key words: bioactive compounds, medicinal mushrooms, polysaccharides, therapeutic l o c metabolites, triterpenoids. i M e d a n Recibido 17 de marzo 2011; aceptado 17 de noviembre 2011. a c i x Received 17 March 2011; accepted 17 November 2011. e M a t s i v Introduction e as well as being a key ingredient in the formulation of tonics R 1 1 and sedatives (Lee et al., 2005).
