SINOPSIS

Various species of the genus Ganoderma have been used for centuries according to oriental tradition as a source of medicines and nutrients. A chemical study of the fruiting bodies and mycelial culture of G. oerstedii was carried out with the idea of isolating and characterizing active natural components present to make use of their potential pharmaceutical application in Mexico. The fruiting bodies and mycelial culture of G. oesrtedii were lyophylized and extracted one after the other with hexane, chloroform, and methanol. Following this process, each substance was extracted separately by using column chromatography. From fruiting bodies eight metabolites, five sterols (ergosta-7,22-dien-3β-ol, ergosterol peroxide, ergosterol, cerevisterol, and ergosta-7,22-dien-3-one) as well as three terpene compounds (ganodermanondiol, ganoderic acid Sz, and ganoderitriol M) were obtained from fruiting bodies. From the mycelial culture three metabolites, two sterols (ergosterol and cerevisterol), and a new terpene compound (ganoderic acetate from the acid) were obtained. These structures were established based on a spectroscopic analysis mainly using nuclear magnetic resonance and a comparison with data already established.
