A new sesquineolignan moricitan A (1), a new natural product 4-methoxy isoamericanin A (2), a new anthraquinone 1,3-dihydroxy-2,5-dimethoxy-6-(methoxymethyl)anthracene-9,10-dione (7), and seven known compounds 3~6 and 8~10 were obtained from the seeds of Noni. The structures were elucidated using comprehensive spectroscopic methods, and the absolute configuration of 1 was established based on quantum-chemical electronic circular dichroism calculations. The inhibitory activity of all the compounds on NO production in lipopolysaccharide-induced (LPS) mouse leukemia cells of monocyte macrophage (RAW 264.7) cells was evaluated. Compound 1 and 9'-ethyl americanol A (3) exhibited stronger anti-inflam- matory activity in vitro with IC50 values of (2.52±0.22) and (5.46±0.89) μmol/L to that of dexamethasone [IC50=(65.39±1.02) μmol/L], respectively.
