title: New lanostane triterpene lactones from the Vietnamese mushroom Ganoderma colossum (FR.) C. F. BAKER.
abstract: Four new lanostane triterpene lactones (colossolactone I, colossolactone II, colossolactone III and colossolactone IV) were isolated from the Vietnamese mushroom Ganoderma colossum (FR.) C. F. BAKER along with five known compounds. The structures of the new compounds were determined on the basis of MS, NMR and circular dichroism.
