Abstract A new cadinane-type sesquiterpenoid, microporotriol (1), together with four known compound, 5-methylresorcinol (2), (22E,24R)-ergosta-4,6,8(14),22-tetraen-3-one (3), (22E,24R)-ergosta-5,7,22-trien-3β-ol (4), (22E,24R)-5α,8α-epidioxy-ergosta-6,22-dien-3β-ol (5), were isolated from the fermentation broth of the wood decaying fungus Microporus affinis HFG829. The structures of the compounds were established by extensive spectroscopic methods, including 1D & 2D NMR, along with HRMS spectroscopic analysis. The relative configuration of 1 was confirmed by NMR calculation. Compound 1 was evaluated for the cytotoxicity against five human cancer cell lines. Graphical abstract
