从诺丽种子中分离纯化得到一个新的倍半木脂素moricitan A (1), 一个新天然产物4-甲氧基异美洲素A (2), 一个新的蒽醌2,4-二羟基-3,8-二甲氧基-7-(甲氧基甲基)-9,10-蒽二酮(7)和7个已知的化合物3~68~10, 其结构通过多种现代波谱技术进行确定, 化合物1的绝对构型通过圆二色谱(ECD)计算确定. 评价了所有化合物对脂多糖(LPS)诱导小鼠巨噬细胞RAW264.7产生一氧化氮(NO)的抑制作用, 化合物1和9'-ethyl americanol A (3)表现出较好的抗炎活性, 其IC50分别为(2.52±0.22)和(5.46±0.89) μmol/L, 强于阳性对照地塞米松[IC50为(65.39±1.02) μmol/L].

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.
