Abstract:

A new anthraquinone, 1,5,15-tri-O-methylmorindol (1), and two new saccharide fatty acid esters, 2-O-(beta-D-glucopyranosyl)-1-O-hexanoyl-beta-D-gluropyranose (4) and 2-O-(beta-D-glucopyranosyl)-1-O-octanoyl-beta-D-gluropyranose (5), have been isolated from a methanol extract of the fruits of Morinda citrifolia (noni) along with 10 known compounds, namely, two anthraquinones (2, 3), six saccharide fatty acid esters (6-11), an iridoid glycoside (12), and a flavanol glycoside (13). Upon evaluation of six compounds (5-7, 9, 10, and 13) for inhibitory activity against 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced inflammation (1 microg/ear) in mice, four saccharide fatty acid esters, 5-7 and 9, exhibited potent anti-inflammatory activity, with ID50 values of 0.46-0.79 mg per ear. In addition, when compounds 1-13 were evaluated against the Epstein-Barr virus early antigen (EBV-EA) activation induced by TPA, all of the compounds exhibited moderate inhibitory effects (IC50 values of 386-578 mol ratio/32 pmol TPA).
