Abstrakt: Rhotomentodiones C-E, three new polymethylated phloroglucinol meroterpenoids with diverse configurations, were isolated from the twigs and leaves of Rhodomyrtus tomentosa. Their structures and absolute configurations were established mainly by means of comprehensive spectroscopic data and electron circular dichroism (ECD) calculation. Among them, Rhotomentodione D (2) exhibited both antibacterial activity with an MIC value of 12.5 μg/mL against Propionibacterium acnes and AChE inhibitory activity with an IC 50 value of 22.9 μm.
