The new compound was determined as 3-hydroxy-1-(1,7-dihydroxy-3,6-dimethoxynaphthalen-2-yl)propan-1-one (1). In the biological activity assay, compound 1 disglayed prominent antibacterial activity with a MIC90 value of (48±4) mg•L⁻¹ for methicillin resistant Staphylococcus aureus (MRSA) strain which was stronger than that of the positive control levofloxacin with a MIC90 value (58±5) mg•L⁻¹.
