Objective For the purpose of finding new agents, the chemical study on Ganoderma resinaceum was carried out. Methods The chemical constituents from the dried fruiting bodies of G. resinaceum were isolated by column chromatographic methods of silica gel, MCI-Gel resin, and high performance liquid chromatography. The structures were elucidated by spectroscopic methods, including extensive 1D and 2D NMR techniques. Results Four compounds including one new meroterpenoid were isolated from this fungus. Their structures were identified as ganoresinains F (1), 3β,7β,15β-trihydroxy-11,23-dioxo-lanost-8,16-dien-26-oic acid (2), ganoderic acid XL2 (3) and 2,3-dihydro-4(1H)-quinolone (4). Conclusion Compound 1 is a new compound and named as ganoresinains F (1).
