Structures of new terpenoid constituents of Ganoderma lucidum (Fr.) KARST (Polyporaceae).

Abstract

Eight new terpenoid constituents named ganoderenic acids A (1), B (2), C (3) and D (4), ganoderic acids E (5), F (6), and G (7), and lucidenic acid D (8) were isolated from dried fruiting bodies of the fungus, Ganoderma lucidum (Fr.) KARST (Polyporaceae) and their structures were determined on the basis of spectral data and some chemical interconversions.
