Abstrakt:	An ethanol-insoluble, high molecular weight fraction was collected from the juice of Morinda citrifolia fruit grown in Viet Nam. The fraction is composed primarily of carbohydrate (67% (w/w)). The polysaccharide fraction consists predominantly of GalAp (53.6mol%), Araf (13.6mol%), Galp (17.9mol%) and Rhap (9.5mol%). Glycosyl linkage analysis suggests the polysaccharide fraction contains mostly the pectic polysaccharides, homogalacturonan (4-GalAp), rhamnogalacturonan I (4-GalAp, 2-Rhap, 2,4-Rhap), arabinan (5-Araf, 3,5-Araf, t-Araf), type I arabinogalactan (4-Galp, 3,4-Galp, t-Araf) and beta-glucosyl Yariv-binding type II arabinogalactan (3,6-Galp, t-Araf). Low levels of xyloglucan (4-Glcp, 4,6-Glcp, t-Xylp, t-Fucp), heteroxylan (4-Xylp) and heteromannan (4-Manp) are also present.
