One new lignan derivative 2,3-dimethyl-4-(4′-hydroxy-3′,5′-dimethoxyphenyl)-6-hydroxy-7-methoxy-naphthalene (1), together with four known analogues (2-5), were isolated from acetone extract of the fruiting bodies of Ganoderma lipsiense collected in the Hainan Province, China. Their structures were elucidated by the detailed analysis of comprehensive spectroscopic data. Compound 1 showed insecticidal activity against newly hatched karvae of Helicoverpa armigera Hubner. Compounds 1-5 showed moderate antibacterial activity against Staphylococcus aureus with the same MIC value of 1.25 μg/mL.
