STUDIES ON CONSTITUENTS OF GANODERMA CAPENSE Ⅳ. THE CHEMICAL STRUCTURES OF GANOINE, GANODINE AND GANODERPURINE

Two novel pyrrole alkaloids-ganoine and ganodine and a novel purine alkaloid ganoderpurine have been isolated from the mycelium of Ganoderma capense (Lloyd)Teng (Polyporaceae) obtained by submerged fermentation. On thebasis of spectroscopic data their structures were elucidated, ganoine is N-isopentyl-5-hydroxymethyl-pyrryl alldehyde. Ganodine is N-phenylethyl-5-hydroxymethyl-pyrryl aldehyde and ganoderpurine is N⁹-(α,α dimethyl-γ-oxobutyl) adenine.
