  • Title: Noniosides E - H, new trisaccharide fatty acid esters from the fruit of Morinda citrifolia (Noni).
    Author: Dalsgaard PW, Potterat O, Dieterle F, Paululat T, Kühn T, Hamburger M.
    Journal: Planta Med; 2006 Nov; 72(14):1322-7. PubMed ID: 17051459.
    Abstract:
    Four new trisaccharide fatty acid esters named noniosides E - H ( 4 - 7) were isolated from the fruit of Morinda citrifolia (Noni) by a combination of Sephadex LH-20, high-speed countercurrent chromatography (HSCCC) and semipreparative HPLC. Their structures were elucidated by high resolution mass spectrometry and 1D- and 2D-NMR as 2,6-di- O-(beta-D-glucopyranosyl)-1-O-hexanoyl-beta-D-glucopyranose (4), 2,6-di-O-(beta-D-glucopyranosyl)-1-O-decanoyl-beta-D-glucopyranose (5), 2-O-(6-O-octanoyl-beta-D-glucopyranosyl)-6-O-(beta-D-glucopyranosyl)-1-O-octanoyl-beta-D-glucopyranose (6), and 2-O-(6-O-hexanoyl-beta-D-glucopyranosyl)-6-O-(beta-D-glucopyranosyl)-1-O-octanoyl-beta-D-glucopyranose or 2-O-(6-O-octanoyl-beta-D-glucopyranosyl)-6-O-(beta-D-glucopyranosyl)-1-O-hexanoyl-beta-D-glucopyranose (7), respectively. In addition, an HPLC-MS analysis of a methanolic extract of the fruit powder revealed the presence of further derivatives including new disaccharide and trisaccharide esters with fatty acid residues of various lengths.
