Secondary metabolites from Ganoderma lucidum and Spongiporus leucomallellus

Ganoderma lucidum contains the steroidester ergosta-7,22-diene-3β-yl pentadecanoate (3) while Spongiporus leucomallellus contains the two triterpene acids named spongiporic acids A (11) and B (12). Antimicrobial activities of spongiporic acid A and cytotoxic activities of 5,8-epi-dioxy-24-methylcholesta-6,9(11),22-triene-3β-ol were investigated.
