摘要
A new fatty acid ester disaccharide, 2-O-(beta-D-glucopyranosyl)-1-O-(2E,4Z,7Z)-deca-2,4,7-trienoyl-beta-D-glucopyranose (1), a new ascorbic acid derivative, 2-caffeoyl-3-ketohexulofuranosonic acid gamma-lactone (2), and a new iridoid glycoside, 10-dimethoxyfermiloside (3), were isolated along with 13 known compounds (4-16) from fermented noni fruit juice (Morinda citrifolia). The structures of the new compounds, together with 4 and 5, were determined by 1D and 2D NMR experiments, as well as comparison with published values. Compounds 2 and 7 showed moderate inhibitory activities in a TNF-alpha-induced NF-kappa B assay, and compounds 4 and 6 exhibited considerable quinone reductase-1 (QR1) inducing effects.
