Novel Mycelial Components, Ganoderic Acid Mg, Mh, Mi, Mj and Mk, from the Fungus Ganoderma lucidum

Abstract
Five novel C30 triterpenoids, ganoderic acids Mg (10), Mh (11), Mi (12), Mj (13) and Mk (14), were isolated from the mycelial mat of a G. lucidum strain, which produces C27 lucidenic acids in the fruiting body. Their structures were determined by spectroscopic analysis and chemical conversion.
